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.

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.
Congenital Infiltrating Lipomatosis of the Face With Cerebral Abnormalities
(Springer-verlag, 2000) Unal, O; Cirak, B; Bekerecioglu, M; Kutluhan, A; Ugras, S; Tali, T
The aim of this study was to describe a possible variant of encephalo-craniocutaneous Lipomatosis syndrome. Three cases of congenital infiltrating lipomatosis of the face, associated with cutaneous, subcutaneous, and cerebral abnormalities: are presented. This neurocutaneous syndrome appears very similar to encephalo-craniocutaneous lipomatosis syndrome but lacks the typical eye lesions.
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.
Dural Arteriovenous Malformation: a Rare Cause of Epilepsy in Childhood
(Neurol Soc india, 2001) Caksen, H; Unal, O; Tombul, T; Cesur, Y; Abuhandan, M
A 3 year and 6 month old girl with epilepsy associated with dural arteriovenous malformation (DAVM), diagnosed on the MRI, is presented to emphasise the importance of DAVM in the aetiology of childhood epilepsy.
Fronto-Orbitonasal Intradiploic Meningioma in a Child
(Karger, 2000) Cirak, B; Guven, MB; Ugras, S; Kutluhan, A; Unal, O
Intradiploic meningioma, which may be classified as a subgroup of intraosseous meningioma, is a rarely encountered disorder. To date, less than 10 cases have been reported. Here, we report a case of fronto-orbito-nasal intradiploic meningioma, A 12-year-old female with exophthalmos and diplopia was operated on for a cranial intradiploic mass lesion. Histopathological evaluation of the specimen confirmed the diagnosis of intradiploic psammomatous meningioma. Her exophthalmos did not change, but the diplopia disappeared. This case is unique in that it is an extensive case of intradiploic meningioma of the orbital roof and frontal base in a child. Intradiploic meningiomas generally are of psammomatous type. Especially tumors adjacent to the orbita cause exophthalmos; cases located on the other side of the calvarium may not cause any symptom or sign other than headache or sometimes a mass on the scalp. Treat ment, as with meningiomas located in the intracranial cavity, is total resection of the lesion. Copyright (C) 2000 S. Karger AG. Basel.

Mr Fluoroscopy-Guided Transthoracic Fine-Needle Aspiration Biopsy: Feasibilitty
(Radiological Soc North America, 2003) Sakarya, ME; Unal, O; Ozbay, B; Uzun, K; Kati, I; Ozen, S; Etlik, O
The purpose of this study was to evaluate the feasibility of using an open-configuration magnetic resonance (MR) imaging system with MR fluoroscopic guidance to perform percutaneous transthoracic fine-needle aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsies were performed with MR fluoroscopic guidance in 14 patients. The masses were 2-7 cm in diameter (mean, 4.1 cm). The needle was positioned by using a free-hand technique with MR fluoroscopic guidance. The needle tip reached the target lesion, and biopsy was performed. Analysis of the biopsy specimens facilitated a specific diagnosis in all patients. Pneumothorax was noted in two patients (14%) with chronic obstructive pulmonary disease. Study results showed that the described MR fluoroscopy-guided transthoracic biopsy technique can be used safely and successfully for lung masses. MR fluoroscopy can be used to reach the target lesion easily and accurately. (C) RSNA, 2003.

Seasonal and Environmental Temperature Variation in the Occurrence of Ischemic Strokes and Intracerebral Hemorrhages in a Turkish Adult Population
(Taylor & Francis Ltd, 2002) Anlar, O; Tombul, T; Unal, O; Kayan, M
Seasonal and weather influence on the incidence of cerebrovascular disease has been reported previously. The aim of this retrospective study was to determine whether the time of onset of ischemic strokes (IS) and intracerebral hemorrhages (ICH) were associated with the environmental temperature or the time, as a month or season, in our region. We analyzed the monthly and seasonal incidence of stroke between 1997 and 2001. Four hundred and fifty-one cases were admitted to our. clinic (IS; n = 288 and ICH; n = 163), and aged from 16 to 94 years. The study was carried out in province of Van in eastern Turkey. The present study demonstrated a peak occurrence of IS in August (n = 41). For ICH, we observed a peak occurrence in July (n = 23). The highest number of IS occurred in summer (n = 108), the most moderate amount in autumn (n = 81), and the least in spring (n = 38). The hemorrhagic events were hi-hest in summer (n = 58), most moderate in winter (n 61), and lowest in spring (n = 31) and autumn (n = 32). There Was a significantly greater incidence of IS and ICH during the summer than any other season in the province of Van, Turkey. This may reflect the role of weather temperature in the development of stroke and allow us to take preventive measures.
Total Bilateral Carpal Coalition With Carpometacarpal Fusion: One Case
(Masson Editeur, 2001) Tuncay, I; Akpinar, F; Unal, O; Aydinlioglu, A
Carpal coalition may involve more than two carpal bones wich is more common when coalition occurs as part of a syndrome of congenital malformations. We describe an unusual case of congenital complete entire carpal coalition with massive carpometacarpal coalition except the first carpometacarpal joint and abnormal distal radioulnar joint bilaterally. In addition, radiocarpal joint surfaces were slightly irregular but compatible. There were abnormal distal radioulnar joints and ulnar styloids articulated with the ulnar side of the lunate of the both wrists.
