Brain Abscess Drainage by Use of Mr Fluoroscopic Guidance
(Amer Soc Neuroradiology, 2005) Ünal, O; Sakarya, ME; Kiymaz, N; Etlik, O; Kayan, M; Kati, I; Harman, M
We describe herein the use of MR fluoroscopic guidance in the drainage of abscess cavities. We percutaneously drained 12 brain abscesses in 11 patients. A 0.3T open MR imaging system was used. Sixteen drainages were performed in 12 abscesses. Repeat drainage was needed in three recurrences and one residual lesion. No serious complications were seen. MR fluoroscopy-guided percutaneous brain abscess drainage in an open MR imaging system is feasible.

Left Hemisphere and Male Sex Dominance of Cerebral Hemiatrophy (dyke-Davidoff Syndrome)
(Elsevier Science inc, 2004) Ünal, Ö; Tombul, T; Cirak, B; Anlar, Ö; Incesu, L; Kayan, M
Although radiological findings of cerebral hemiatrophy (Dyke-Davidoff-Masson Syndrome) are well known, there is no systematic study about the gender and the affected side in this syndrome. Brain images in 26 patients (mean aged 11) with cerebral hemiatrophy were retrospectively reviewed. Nineteen patients (73.5%) were male and seven patients (26.5%) were female. Left hemisphere involvement was seen in 18 patients (69.2%) and right hemisphere involvement was seen in eight patients (30.8%). We conclude that male gender and left side involvement are frequent in cerebral hemiatrophy disease. (C) 2004 Elsevier Inc. All rights reserved.
Mr Findings in Cardiac Hydatid Cyst
(Elsevier Science inc, 2002) Sakarya, ME; Etlik, O; Sakarya, N; Ozen, S; Temizoz, O; Evirgen, O; Kayan, M
We report a case of a 23-year-old man with a cardiac hydatid cyst involving the left ventricle wall. The diagnosis of the cyst was obtained by magnetic resonance (MR) imaging. He was operated on for cardiac hydatid cyst using enucleation and capitonnage procedure under extracorporeal circulation. Histopathologic study confirmed hydatid cyst diagnosis.

Mri Demonstration of Cervical Spondylodiscitis and Distal Full-Length Bilateral Paraspinal Cold Abscesses Successfully Treated by Drug Regimen Only
(Springer, 2004) Ünal, Ö; Kayan, M; Akpinar, F; Çankaya, H; Akdeniz, N
Objective: Cold abscesses, although common in spinal tuberculosis, are usually localized to the level of infection, follow tissue planes, and may extend into the spinal canal at any level. They may cause symptoms resulting from neurovascular compression, hemorrhage, and direct mass effect. Design and patients: We present an unusual case of cervical tuberculous spondylodiscitis in a 25-year old man with a cold abscesses involving the retropharyngeal, mediastinal, and retroperitoneal areas bilaterally. The abscess tracked from the neck to the psoas muscles bilaterally. Following the diagnosis the patient received 9 months of antituberculous therapy. Results: MRI showed resolution on medical treatment alone. Conclusions: Even in the presence of massive paravertebral cold abscesses medical treatment alone may well suffice for this common worldwide disorder. MRI is ideal for monitoring regression of massive abscesses in deep anatomical locations.
Mri Findings of Hepatic Alveolar Echinococcosis
(Elsevier Science inc, 2003) Harman, M; Arslan, H; Kotan, C; Etlik, O; Kayan, M; Deveci, A
Diagnosis of liver infestation by alveolar echinococcosis (AE) is based on serologic, sonographic and computed tomography (CT) findings. Experience with magnetic resonance imaging (MRI) demonstrates that features of this disease are limited. CT and MRI findings of 14 cases with hepatic AE were compared in this report. We have described the MRI appearance of hepatic AE, which exhibits variable signal intensities on T1- and T2-weighted images. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases, a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cyst. MRI than by CT was more easily identified central necrosis. However, MRI seemed to be less effective than CT in allowing us to reach a positive diagnosis, due to its inability to show microcalcifications. In addition, MRI may not reveal small lesions. In most cases, T1-weighted images revealed more clearly than CT did the margins of the lesions and the hepatic extension, especially to hepatic veins, vena cava and perihepatic spaces.

Peroral Ct Enterography With Lactulose Solution
(Amer Roentgen Ray Soc, 2005) Arslan, H; Etlik, Ö; Kayan, M; Harman, M; Tuncer, Y; Temizöz, O
Objective: The objective of our study was to evaluate lactulose solution as a new oral contrast agent with the use of peroral CT enterography to determine the adequacy of luminal distention and conspicuity of the bowel wall. CONCLUSION. Peroral CT enterography performed with lactulose solution is a simple and noninvasive method of evaluating the small bowel by obtaining good distention. It can also be used at routine abdominal examinations as a negative contrast agent instead of iodinated oral contrast medium, especially for CT angiography.
Popliteal Artery Pseudoaneurysm
(John Wiley & Sons inc, 2004) Harman, M; Irmak, H; Arslan, H; Arslan, Ü; Kayan, M
Brucellosis is still a public health problem, particularly in developing countries. After the primary infection subsides, a chronic stage characterized by nonspecific manifestations can develop, during which it may not be possible to isolate Brucella organisms and agglutination test titers may or may not be high. We present the case of a 49-year-old man who had only nonspecific symptoms and a 2-month history of a pulsatile painful swelling in his right popliteal region. He had no history of trauma or surgery in that region, but he did ingest unpasteurized milk products. The patient's agglutination test titers were high, and Brucella melitensis was isolated from a bone marrow culture. Color Doppler sonography, T2-weighted MRI, and digital subtraction angiography were performed. Treatment with ultrasound-guided compression of the pseudoaneurysm failed because of high blood flow in its neck. Aneurysmectomy was undertaken, and the excised material was consistent with that from a mycotic pseudoaneurysm. Although both MRI and angiography provided useful information, the color Doppler sonography findings were characteristic of a pseudoaneurysm in the popliteal artery, and only that modality could detect the flow dynamics within the pseudoaneurysm.

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.
