Öğe Dural cavernous hemangioma originating from superior petrosal sinus(2002) Koçaki A.; Çayli S.R.; Önal S.Ç.; Kutlu R.; Aydin N.E.Cavernous angiomas of the dura are rare and have been described in the literature particularly in the middle cranial fossa. We present a case of cavernous hemangioma of the middle cranial fossa arising from the superior petrosal sinus. In our review of the literature, this is the 2nd report describing a cavernous hemangioma in such a location.Öğe Pregnant woman with subarachnoid hemorrhage and multiple intracranial aneurysms: A case report(Turkish Neurosurgical Society, 2006) Koçak A.; Ateş O.; Çayli S.R.; Saraç K.Aneurysmal subarachnoid haemorrhage (SAH) during pregnancy is rare but serious obstetric complication and may be confused with eclampsia. SAH occurs more often in primiparae and in the third trimester of pregnancy. The hemodynamic and endocrine changes play an important role in the growth and rupture of aneurysms. There are no differences in the clinical course of SAH among pregnant and non-pregnant patients. A 19-yr-old woman who was 34-weeks pregnant presented with an SAH, secondary to a ruptured left posterior communicating artery (L-PComA) aneurysm. The angiogram revealed multiple cerebral aneurysms. Following initial recovery, she subsequently underwent simultaneous elective caesarean section and clipping of the aneurysms. The management and pathogenesis of a ruptured aneurysm during pregnancy is discussed.Öğe An unusual complication of ventriculo-peritoneal shunt: Cerebrospinal fluid cyst in liver(Elsevier BV, 2004) Koçak A.; Baysal T.; Çayli S.R.; Ateş Ö.; Önal Ç.Internal drainage of cerebrospinal fluid (CSF) to the abdominal cavity via ventriculo-peritoneal (VP) shunt is commonly used for the treatment of hydrocephalus. Many types of shunt systems are available, but all are liable to complication. Some of these complications occur frequently and are therefore well known. However, there are other complications which occur rarely, including cerebrospinal fluid cyst in liver. We report a 15-year-old female who developed a CSF cyst in the liver due to mislocation of the peritoneal catheter which was successfully treated by simple repositioning. © 2004 Elsevier Ireland Ltd.

Case Report(American Association of Neurological Surgeons, 2001) Çayli S.R.; Önal Ç.; Koçak A.; Onmuş S.H.; Tekiner A.Tuberculosis continues to be a major public health concern, especially in developing countries. Many types of neurotuberculosis have been described, but there is only one previously reported case of subdural empyema caused by tuberculous bacilli. A 1-year-old boy who had been treated for pulmonary tuberculosis was referred to the authors' institution with a diagnosis of right frontoparietal extraaxial abscess formation. Computerized tomography and magnetic resonance imaging revealed an extraaxial abscess with no evidence of calvarial infection. A craniotomy was performed to drain the pus, which was located subdurally. A polymerase chain reaction test yielded positive results, and histopathological examination revealed caseation. Antituberculous treatment was started after a diagnosis of subdural empyema with related neurotuberculosis had been made. At the end of a 12-month course of medical therapy, the patient was well with no evidence of tuberculosis.Öğe An unusual presentation of occult spinal dysraphism(2002) Çayli S.R.; Koçak A.; Önal C.; Cucciniello B.Occult spinal dysraphism can lead to irreversible neurological complications, early diagnosis and treatment are necessary. It can be suspected from the presence of any cutaneous abnormality. We report a case with bony spur formation on the top of the 5th lumbar vertebra spinose process covered with skin mimicking a meningocel sac. By the help of this bony spur tethered cord could be diagnosed before any neurological deficit.
