title: Chronic subdural hematoma after endoscopic third ventriculostomy: a case report and literature review.
abstract: Chronic subdural hematoma is a very rarely observed complication after     endoscopic third ventriculostomy (ETV). A 21-year-old male patient was admitted     to our clinic with complaining of headache, weakness and tremor. The fundoscopic     examination revealed slightly indistinct border of the papilla and neurological     examination findings were normal. The cranial computed tomographic (CT) and     magnetic resonance imaging (MRI) findings demonstrated three-ventricular     hydrocephalus due to aqueductal stenosis and ETV was performed. The symptoms got     better after the operation. At 1½ month postoperatively the patient reapplied to     our clinic with a symptom of severe headache. Cranial BT imaging demonstrated     enlargement of subdural hematoma. The hematoma was treated by burr-hole     evacuation and drainage and totally disappeared in the postoperative period. The     follow-up CT scan was evaluated as normal. Nowadays, ETV is accepted as a safe     and an alternative method for the treatment of obstructive hydrocephalus instead     of shunt operation. Chronic subdural hematoma is a rarely observed complication     after ETV.
