    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.

    An unusual presentation of neurotuberculosis: Subdural empyema. 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.
