Abdominal Hydatid Disease: Long-Term Results of Percutaneous Treatment
(Blackwell Munksgaard, 2004) Etlik, O; Arslan, H; Bay, A; Sakarya, ME; Harman, M; Temizoz, O; Unal, O
Purpose: To evaluate the effectiveness of percutaneous treatment under sonographic guidance in abdominal hydatid cysts. Material and Methods: Fifty-two hydatid cysts in 33 patients were treated using a percutaneous approach under sonographic guidance. Forty-five cysts were located in the liver, 6 in the spleen, and I in the pancreas. Forty-nine cysts were type 1, and 3 were type II. Thirty-one cysts in 15 patients were treated with puncture and aspiration of the contents, injection of hypertonic saline solution, and respiration (PAIR); 15 cysts in 14 patients were treated with puncture, aspiration of cyst contents, injection of hypertonic saline solution, drainage, and injection of sclerosing agent (PAIDS); and 6 cysts in 4 patients were treated with puncture, aspiration of cyst contents, injection of sclerosing agent, and re-aspiration (mPAIDS). Hypertonic saline or alcohol was used as a scolicidal agent. The follow-up period was between 17 and 53 months. Results: A decrease in the dimensions of the cysts, solidification of the contents, and irregularity in the walls of cysts, all of which were considered signs of cure, were found in all patients. Recurrence was observed in one case and anaphylaxis in one. Conclusion: Percutaneous treatment of abdominal hydatid cysts is a safe, easily applicable, well-tolerated, and effective method.
Brucellar Spondylodiscitis -: Mri Diagnosis
(Elsevier Science inc, 2001) Harman, M; Unal, Ö; Onbasi, KT; Kiymaz, N; Arslan, H
Early diagnosis of bruccellar spondylodiscitis is often difficult because of the long latent period. Radiographs of the spine, bone scan, and computed tomography (CT) scan provide insufficient data. Among 25 patients with brucellar spondylodiscitis studied by magnetic resonance imaging (MRI), 9 were in the acute stage and 16 were in the chronic stage. MRI is the investigation method of choice in diagnosing brucellar spondylodiscitis. (C) 2001 Elsevier Science Inc. All rights reserved.

Chiasmatic Glioblastoma of Childhood - a Case Report
(Munksgaard int Publ Ltd, 2000) Cirak, B; Unal, O; Arslan, H; Cinal, A
A 6-year-old girl presented with visual deterioration that had progressively worsened over 2 months. MR imaging revealed a sellar, para- and suprasellar lesion. Subtotal tumor resection was performed. Histopathological diagnosis was glioblastoma of the optic chiasma. Chiasmatic glioblastoma is rare in adults and extremely uncommon in children. Surgical resection implies a risk of severe endocrinologic and opthalmologic complications.

The Club-Shaped Cord Terminus in Siblings With Caudal Agenesis
(Springer verlag, 1999) Ünal, Ö; Sakarya, ME; Arslan, H
We report a rare instance of caudal agenesis occurring in siblings, with MRI. Both our patients had a club-shaped spinal cord, ending at T11. Radiological and urological findings are presented.
Comparison of Thickness Measurements in Cutaneous and Subcutaneous Lesions Preoperatively (By Ultrasonography) and Postoperatively (By Ruler)
(Springer verlag, 1998) Bekerecioglu, M; Arslan, H; Ugras, S; Karakok, M; Akpolat, N
Vertical thickness of cutaneous and subcutaneous lesions cannot be assessed accurately by simple examination. To achieve this ultrasonography was performed preoperatively and ruler assessment postoperatively. These measurements were then compared and evaluated using the Wilcoxon test. The results were not statistically significant (p=0.6592, z=0.4410). Cutaneous and subcutaneous ultrasonography is a simple, quick, accurate method of assessing lesion thickness.
Contrast-Enhanced Ct and Mri Findings of Atypical Hepatic Echinococcus Alveolaris Infestation
(Springer, 2005) Etlik, Ö; Bay, A; Arslan, H; Harman, M; Kösem, M; Temizöz, O; Dogan, E
Diagnosis of liver infestation by Echinococcus alveolaris (EA) is based on serological and radiological findings. In this report, we present a 15-year-old girl with atypical hepatic EA infestation showing central punctate calcifications and contrast enhancement on the portal and late phases of CT and MRI. CT showed a hypodense mass involving more than half of the liver with prominent central calcifications. MRI revealed hypointense signal of the infiltrative mass on both T1- and T2-weighted images. Contrast enhancement is a unique finding in hepatic EA infestation that may cause difficulties with diagnosis. MRI may provide invaluable information in the diagnosis of EA infestation of the liver, either by disclosing the infiltrative pattern of infestation without significant effect to vascular structures, or by the signal characteristics.
The Diagnosis by Fine Needle Aspiration Biopsy of Hydatid Cyst of the Pancreas
(Assoc Soc Scientifique Med Belges, 1997) Ugras, S; Sakarya, ME; Arslan, H; Bozkurt, M; AKdeniz, H
We describe a case of pancreatic hydatid cyst in which the definitive diagnosis was made at fine needle aspiration cytology. The most common site of hydatid cyst is the liver (65%), followed by the lungs (25%). The hydatid cyst of the pancreas is rare since it accounts for less than 1% of the various sites of hydatid disease. The diagnosis may be difficult when the presentation is that of an unexplained epigastric mass or cyst, despite suggestive radiological and ultrasonographic features. Modern serology tests are positive in up to 80% of the abdominal hydatid cysts. It is mandatory to obtain a fine needle aspiration biopsy for definite diagnosis and for appropriate treatment planning. Surgical removal of the hydatid cyst still remains the most effective treatment.
Duplex and Color Doppler Sonographic Findings in Active Sacroiliitis
(Amer Roentgen Ray Soc, 1999) Arslan, H; Sakarya, ME; Adak, B; Unal, O; Sayarlioglu, M
OBJECTIVE, The aim of this study was to describe the duplex and color Doppler sonographic findings in active sacroiliitis. SUBJECTS AND METHODS. Forty-one joints in 21 patients with active sacroiliitis, 20 sacroiliac joints in 10 patients with osteoarthritis, and 30 sacroiliac joints of 15 asymptomatic volunteers were investigated on duplex and color Doppler sonography. We investigated whether a vessel was present around the posterior portions of sacroiliac joints with color Doppler sonography. When an artery was detected the resistive index (RI) was measured using duplex Doppler sonography in all groups and also after treatment in the patients with active sacroiliitis. RESULTS. Vascularization around the posterior portions of sacroiliac joints was seen in 41 joints of the 21 patients with active sacroiliitis, nine joints of six patients with osteoarthritis, and 13 joints of eight volunteers. The mean RI values were 0.62 +/- 0.13, 0.91 +/- 0.09, and 0.97 +/- 0.03, respectively. In the patients with active sacroiliitis, the mean RT value was 0.91 +/- 0.07 after therapy. The RI values for the patients with active sacroiliitis were significantly different from those of the patients with osteoarthritis (p < .001) and of the volunteers (p < .001). In addition, the RI values were significantly different before and after treatment in the patients with active sacroiliitis (p < .001). CONCLUSION. Vascularization around the posterior portions of sacroiliac joints increased and RI values decreased in patients with active sacroiliitis. Color and duplex Doppler sonography were able to reveal these changes and can be used in the diagnosis of active sacroiliitis and follow-up after treatment. Thus, RI values may be a quantitative indicator for clinical symptoms in patients with active sacroiliitis.
Evaluation of Diaphragmatic Movement With Mr Fluoroscopy in Chronic Obstructive Pulmonary Disease
(Elsevier Science inc, 2000) Ünal, Ö; Arslan, H; Uzun, K; Özbay, B; Sakarya, ME
The aim of this study was to show reduction of the diaphragmatic excursion with MR fluoroscopy in patients with chronic obstructive pulmonary disease (COPD) and to compare the results with pulmonary function test (PFT). The study included 13 men and 10 women (average age 56.2) with COPD, and 9 men and 6 women (average age 55.8) as a control group. MR fluoroscopy images with Spoiled Gradient-echo pulse sequence was obtained during deep inspiration and expiration. After examination, over cine-loop display, the highest and lowest positions of the diaphragm were identified and the distance of excursion was measured. Differences in the diaphragmatic excursion between patient and healthy subjects were compared. We have also compared MR fluoroscopy results with PFT. In each person of both groups, excursion of the diaphragm was demonstrated clearly in cine-loop display. Differences of excursion between deepest and highest point of diaphragm were on average 26 and 20 mm, respectively, in the right and left side in patients and 69 and 56 mm in healthy group. Significant correlation was found between expiratory volume in 1 s and MR fluoroscopy results. MR fluoroscopy study showed that there were significant statistical differences in diaphragmatic excursion between patients with COPD and healthy subjects. Expiratory volume in 1 s is closely associated with the diaphragmatic excursion. MR fluoroscopy would seem to be a useful method for showing diaphragmatic excursion. (C) 2001 Elsevier Science Inc.

Evaluation of the Patellofemoral Joint With Kinematic Mr Fluoroscopy
(Elsevier Science inc, 2002) Harman, M; Dogan, A; Arslan, H; Ipeksoy, U; Vural, S
Objective: The aim of this study was to evaluate the diagnostic effectiveness of kinematic magnetic resonance fluoroscopy (KMRF) on patients with patellofemoral incongruency. Materials and methods: 17 patients (20 knees) and 10 healthy volunteers (20 knees), all men (mean age 29.4 years, S.D. 9, range 16-50), were included to our study. Only male subjects were studied because of potential biomechanical differences between sexes. KMRF was used to perform kinematic MR imaging of patellar alignment and tracking in 10 healthy Subjects and 17 patients with a provisional clinical diagnosis of abnormal patellofemoral joints. The patellofemoral joints were examined with the knee in different angles of active flexion. At each knee position, real time kinematic and axial MRF image Was used to focus on the sagittal plane, followed by an axial image focused through the middle of the patella. Three angles were measured: patellar tilt angle (PTA), sulcus angle (SA) and congruence angle (CA). Results: Five patterns of malalignment were identified and studied. Two patellofemoral joints were normal, 10 had lateralization of the patella, 2 had patellar tilt, 2 had lateralization and patellar tilt (i,e. excessive lateral pressure syndrome) and 4 had medialization of the patella. Conclusion: KMRF is an effective method in evaluating patellofemoral incongruency. Short time duration of investigation, ability to get nearly real time images, suitable temporal contrast resolution and investigation from very different angles of knee are important advantages of the method.

Fibrosing Mediastinitis and Thrombosis of Superior Vena Cava Associated With Behcet's Disease
(Elsevier Sci Ireland Ltd, 2003) Harman, M; Sayarlioglu, M; Arslan, H; Ayakta, H; Harman, E
We present CT, MRI and venography findings in 13-year boy with mediastinal fibrosis and superior vena cava (SVC) thrombosis associated with Behcet's disease. Fibrosing mediastinitis is an excessive fibrotic reaction that occurs in the mediastinum and may lead to compression of mediastinal structures (especially vascular). This condition is usually idiopathic, though many (and perhaps most) cases in the USA are thought to be caused by an abnormal immunologic response to Histoplasma capsulatum infection. SVC syndrome secondary to extrinsic compression by mediastinal fibrosis combined with Behcet's disease has rarely been described. Radiological investigations of this syndrome are necessary to avoid a useless anticoagulant therapy. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.
Free Hydatid Cyst Only Covered With Germinative Membrane Disrupted From Fibrotic Capsule in the Peritoneal Cavity: a Case Report
(Assoc Soc Scientifique Med Belges, 1998) Arslan, H; Sakarya, ME; Bozkurt, M; Dilek, FH; Yilmaz, Y; Dilek, ON; Er, R
Echinococcosis, an endemic disease on the Asian continent, is caused by ecinococcus granulosus and rarely ecinococcus alveolaris. Although it occurs frequently in the liver and the lung, it can be localized in all tissues and organs. The purpose of this study is to report a rare localization and the complication of hydatid cyst in the pelvis : it pushed forward and upward the urine bladder and there was bilateral hydroureteronephrosis causing uraemia because of outflow obstruction. To our knowledge, a similar case has not been published before in English literature.
Frequency of Sinusitis in the Patients With Pneumonia
(Elsevier Science inc, 2002) Özbay, B; Arslan, H
The aim of this study was to investigate the frequency of sinusitis in patients with pneumonia. Among 50 Consecutive patients with pneumonia, 19 cases, which had Waters' roentgenograms in their Cites. were retrospectively reviewed in relation with sinusitis. Sixteen of them had sinusitis signs in their roentgenograms. The sinusitis frequency was 84% in patients with pneumonia who had paranasal sinus roentgenograms. These findings suggest that sinusitis may be an important causative factor for pneumonia and that it Should be considered when evaluating a patient with pneumonia. (C) 2002 Elsevier Science Inc.

Hepatic Cavernous Hemangiomas -: Patterns of Contrast Enhancement on Mr Fluoroscopy Imaging
(Elsevier Science inc, 2002) Ünal, Ö; Sakarya, ME; Arslan, H; Tuncer, I; Etlik, Ö
Purpose: The purpose of this study was to assess the patterns of contrast enhancement of hepatic hemangiomas on gadolinium-enhanced MR fluoroscopy imaging prospectively. Method: Investigation was performed on a 0.3-T open MR unit. Gadolinium-enhanced MR fluoroscopy images were obtained in 24 patients with 28 hepatic hemangiomas. Each MR fluoroscopy image was obtained in 2 s and MR fluoroscopy lasted for 10-25 min for each investigation. Results: Three patterns of contrast enhancement were observed in 24 patients on MR fluoroscopy images. Four small lesions were not detected on MR fluoroscopy images. Uniform enhancement was seen in nine lesions (29%), peripheral nodular enhancement progressing centripetally to uniform enhancement was seen in nine lesions (29%), and peripheral nodular enhancement with persistent central hypointensity was seen in six lesions (22%). Conclusion: Enhanced MR fluoroscopy technique could obtain dynamic images of hepatic hemangiomas. It can be suggested as a useful technique for the showing of enhancement of hepatic hemangiomas, keeping in mind its low sensitivity in the diagnosis of small hemangiomas.

(Springer verlag, 1997) Dilek, ON; Bozkurt, M; Arslan, H; Kisli, E; Poyraz, N; Berberoglu, M
Background: This study was designed to assess differences between pre- and postoperative herniography and ultrasonography in inguinal hernia performed laparoscopically with balloon dissection and mesh without suture, Methods: Pre- and postoperative herniographic and ultrasonographic findings were analyzed in ten consecutive patients, Postoperative ultrasonography was performed on the 3rd and 7th days and herniography was performed on the 7th day, Results: Following the operation both the herniography and ultrasonography were almost normalized to a great extent in nine patients, Overall, minimal impaired continence was recorded by herniography in one patient. Also, we detected nonspecific soft-tissue thickening at the operation site in ultrasonographic examination in four patients, Conclusions: As for inguinal hernias, compared with other operative modalities of treatment, laparoscopic hernia repair with extraperitoneal balloon dissection and mesh without suture is a highly successful procedure and its minimal morbidity is well accepted by the patient.
Incidence of Retro-Aortic Left Renal Vein and Its Relationship With Varicocele
(Springer, 2005) Arslan, H; Etlik, Ö; Ceylan, K; Temizoz, O; Harman, M; Kavan, M
The retro-aortic left renal vein (RLRV) is a malformation characterized by the presence of a vessel that drains the left renal blood up to the inferior vena cava crossing behind the aortic artery. Varicocele is defined as venous dilation of the pampiniform plexus, and the left side is the most commonly affected. Several theories concerning the possible aetiology of varicocele are reviewed in the literature, but RLRV was not mentioned as an aetiologic factor of varicocele. in this study we investigated the percentage of RLRVs and their relation with varicocele. A total of 1,125 contrast-enhanced abdominal CT scans was examined to identify RLRVs. RLRVs were found in nine women (1.6%) and ten men (1.7%). We performed scrotal Doppler ultrasonography (US) for all affected men except one. Varicocele of varying degrees was found in seven of the nine male patients with RLRV (77%). RLRV could be one of the aetiological factors in the development of varicocele, and the cases with RLRV should be examined by scrotal Doppler US for the presence of varicocele.
Monostotic Fibrous Dysplasia Originating From Ethmoid Bone
(Annals Publ Co, 2004) Kutluhan, A; Kiroglu, AF; Yurttas, V; Arslan, H; Özen, S
We present a case of monostotic fibrous dysplasia of the ethmoidal sinus in an 11-year-old boy. This condition is of interest to the otorhinolaryngologist because of the difficulty of differential diagnosis and treatment. This tumorlike growth was not restricted to the right ethmoidal sinus, but also compressed the orbit and the globe. Endoscopic and transnasal removal of the mass with a drill was performed under general anesthesia. No residual tumor was observed 6 months later.
Mr Arthrography in Chondromalacia Patellae Diagnosis on a Low-Field Open Magnet System
(Elsevier Science inc, 2003) Harman, M; Ipeksoy, U; Dogan, A; Arslan, H; Etlik, O
Objective: The purpose of this study was to compare the diagnostic efficacy conventional MRI and MR arthrography (MRA) in the diagnosis of chondromalacia patella (CP) on a low-field open magnet system (LFOMS), correlated with arthroscopy. Subjects and methods: Forty-two patients (50 knees) with pain in the anterior part of the knee were prospectively examined with LFOMS, including T1-weighted, proton density-weighted and T2-weighted sequences. All were also examined T1-weighted MRI after intraarticular injection of dilue gadopentetate dimeglumine. Two observers, who reached a consensus interpretation, evaluated each imaging technique independently. Thirty-six of the 50 facets examined had chondromalacia shown by arthroscopy, which was used as the standard of reference. The sensitivity, specificity and accuracy of each imaging technique in the diagnosis of each stage of CP were determined and compared by using the McNemar two-tailed analysis. Results: Arthroscopy showed that 16 facets were normal. Four (30%) of 13 grade 1 lesions were detected with T1. Four lesions (30%) with T2 and three lesions (23%) with proton-weighted images were detected. Seven (53%) of 13 grade 1 lesions were detected with MRA. Grade 2 abnormalities were diagnosed in two (33%) of six facets with proton density-weighted pulse sequences, two (33%) of six facets with T1-weighted pulse sequences, in three (50%) of six facets with T2-weighted pulse sequences, in five (83%) of six facets with MRA sequences. Grade 3 abnormalities were diagnosed in three (71%) of seven facets with proton density- and T1-weighted images, five (71%) of seven facets with T2-weighted pulse sequences, six (85%) of seven facets with MRA sequences. Grade 4 CP was detected with equal sensitivity with T1-, proton density- and T2-weighted pulse sequences, all showing seven (87%) of the eight lesions. MRA again showed these findings in all eight patients. All imaging techniques were insensitive to grade 1 lesions and highly sensitive to grade 4 lesion, so that no significant difference among the techniques could be shown. Conclusion: All imaging technique studied had high specificity and accuracy in the detection and grading of CP; however, MRA was more sensitive than T1-weighted and proton density-weighted MR imaging on a LFOMS. Although the arthrographic techniques were not significantly better than T2-weighted imaging, the number of false-positive diagnosis was greatest with T2-weighted MRI. (C) 2003 Elsevier Science Inc.
