Case Report: Treatment With Arterial Embolization in a Destroyed Cervical Pregnancy
(2003) Harman, M.; Zeteroglu, S.; Etlik, O.; Arslan, I.
Cervical pregnancy is a rare form of ectopic pregnancy. It is frequently associated with extensive hemorrhage, which, in severe cases, may be stopped only by hysterectomy. We report a case of a destroyed cervical pregnancy simulating cervical cancer. The patient was conservatively managed with simple selective uterine artery embolization without methotrexate administration. Her vaginal bleeding ceased after embolization. No additional treatment was given. The patient resumed normal menstruation two months after embolization.
Endoscopic View and Mri of a Thornwaldt's Cyst of the Nasopharynx
(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2005) Yuca, K.; Etlik, O.; Kiroglu, A. F.; Celebi, S.; Yakut, E.
A Thornwaldt's cyst is an uncommon nasopharyngeal lesion that develops from the remnant of the primitive notochord. A 65-year-old man with a Thornwaldt's cyst is presented in this case report. The patient was diagnosed by rigid nasal endoscopy and magnetic resonance imaging (MRI). These cases are infrequently presented in the English journals. Our study suggested that endoscopic and MRI examinations of the nasopharynx were a simple, rapid, and useful procedure for the diagnosis of the Thornwaldt's cysts.
Multidetector Computed Tomography in the Diagnosis of Parathyroid Adenomas: Contribution of Contrast Enhancement Pattern To Diagnosis
(2004) Harman, M.; Algün, E.; Ayakta, H.; Sakarya, M.E.; Etlik, O.
PURPOSE: Contrast enhancement patterns of parathyroid adenomas in the arterial and venous phases were evaluated with multidetector computed tomography and specificity of the method to characterize the lesions was investigated. MATERIALS AND METHODS: Arterial and venous enhancement patterns of parathyroid adenomas were evaluated retrospectively with multidetector computed tomography in 12 patients. All adenomas were removed surgically and the diagnosis was confirmed histopathologically. An area from the mandibular angle to the aortic arch was scanned with 1.5 mm section thickness in the arterial phase (20 seconds delay time) and venous phase (70 seconds delay time) after bolus injection of 50 ml of iodinated contrast media. Arterial and venous contrast enhancement of parathyroid adenomas was evaluated in the axial and coronal reformat images. RESULTS: Ten (83.3%) of 12 parathyroid adenomas showed a heterogeneous enhancement with a hypodense small central area in the arterial phase and a homogeneous enhancement in the venous phase. However, two small lesions, four and five mm in diameter respectively, showed homogeneous contrast enhancement in the arterial phase unlike the larger lesions which displayed a hypodense center in this phase. CONCLUSION: Dynamic scanning with multidetector computed tomography after contrast administration may be helpful in characterizing parathyroid adenomas.
Posterior Cerebral Artery Involvement in Moyamoya Disease
(2004) Harman, M.; Etlik, O.; Unal, O.; Sakarya, M.E.
A ten-year-old girl arrived at the hospital with progressive loss of muscular strength on the right side of the body. The cranial MRI showed left fronto-parietal ischemia and atrophic changes in the left parietal lobe. Brain MRI initially disclosed a narrow left MCA. MRA and digital angiography confirmed the diagnosis of brain obstructive chronic vascular disease (Moyamoya). Angiography results demonstrated occlusion of the left MCA and right posterior cerebral artery, with Moyamoya vessels. It therefore appears that in some patients Moyamoya disease is accompanied by posterior circulation involvement.

Uterine Leiomyoma Embolization: Role of Power Doppler Ultrasonography
(2003) Harman, M.; Zeteroglu, S.; Sengül, M.; Etlik, O.; Arslan, H.
PURPOSE: The vascularity of uterine leiomyoma was evaluated by power Doppler ultrasonography (PDUS) before and after bilateral uterine artery embolization (UAE) in order to establish the efficacy of the procedure and contribution to the treatment. MATERIALS AND METHODS: UAE was performed in 20 symptomatic patients with uterine leiomyoma. In addition to MRI and gray scale US, patients were evaluated by PDUS to assess the vascularity of the uterus and leiomyomas before and 6 months after the embolization and the findings were compared with angiography. Vascularity was categorized into 3 groups as mild (5 cases), moderate (7 cases) and marked (8 cases). Relationship between the findings of PDUS and treatment results were analyzed statistically by one-way ANOVA and post-hoc Tukey tests. RESULTS: In PDUS except their calcified and degenerated regions leiomyomas displayed more vascularity peripherally than centrally, before the embolization. Six months after the embolization, a decrease of 37%, 44% and 59% was observed in the mass of the leiomyomas that had revealed mild, moderate and marked vascularity before the embolization. Greater mass reduction occurred in leiomyomas with high pre-embolization vascularity (p < 0.05). CONCLUSION: PDUS gives important information about the vascularity of uterine leiomyomas before and after uterine artery embolization, which became a widespread treatment option in recent years. It can be helpful in the selection of patients for uterine artery embolization by revealing the vascularity of the leiomyomas. Also it is a non-invasive and cheap method in the determination of the efficacy of the procedure in the early and late periods after embolization.
The Value of Flexion Mri Acquisition in Detection of Meniscal Tears
(TIP ARASTIRMALARI DERNEGI, 2010) Gündüz, A.M.; Arslan, H.; Avcu, S.; Etlik, O.; Doǧan, A.; Ünal, O.
Aim: The efficiency of MRI of the flexed knee was studied concerning meniscal lesion staging, existence of tears and meniscocapsulary separation (MCS). Method: In our study with 50 cases, saggital TSE Pd/T2W sequences were acquired in flexion position in addition to routine MRI sequences in neutral position. Subtle or apparent tears and MCSs observed on neutral position acquisitions (NPA) were also evaluated with knee in flexion acquisitions (KFA) in order to evaluate additional diagnostic findings. Statistical evaluation was performed using Chi-square and reliability of medical diagnostic tests. Result: There was no statistically significant difference between NPA and KFA concerning meniscal lesion grading (p>0.05). There was no statistically significant difference between NPA and KFA concerning tears due to signal increase extending to the joint surface. On the other hand, KFA contributed in tears due to MCSs (28,6%). Conclusion: KFA is an applicable method in closed system MR devices, does not disrupt patient comfort and is not time consuming. Using this method, additional information can be acquired with high contrast resolution images. KFA seems to be a superior method to NPA in patients with suspected meniscal tears and especially in cases of MCS. Further studies with extended number of patients will increase the reliability of the results.
