Giant acute epidural hematoma after ventriculoperitoneal shunt: a case report and literature review.

Cerebrospinal fluid over-drainage is a common complication of ventriculoperitoneal devices. In terms of haemorrhage, subdural haematomas are usually more frequent lesions than epidural hematomas, which, more rarely, may also be seen after ventricular shunt procedures and may lead to rapid neurological decline and even death unless a surgical procedure can be promptly performed. This study reports the case of a 47 years-old Dandy Walker man, with clinical condition compatible with the diagnosis of normal pressure hydrocephalus submitted to a ventriculoperitoneal shunt with a high fixed pressure valve.

The ventriculoomental bursa shunt.

Object: The aim of this study is to access the efficacy of the omental bursa (lesser sac) as a receptacle of cerebrospinal fluid (CSF) and to use it as an alternative to the ventriculoatrial or ventriculopleural shunts when the peritoneum reduces or loses its CSF absorption capacity.

Methods: Three patients with hydrocephalus presented with malfunctioning of ventriculoperitoneal shunts, secondary to peritoneal blockage caused by previous episodes of shunt infections in two and peritonitis in one patient. All patients underwent previous shunt revisions due to ventriculitis and shunt obstruction ranging from three to eight times.

Cerebral abscess caused by Serratia marcescens in a premature neonate.

Background: Cerebral abscesses are extremely rare in neonates. Serratia marcescens is an unusual cause of sepsis and neurological spread is especially ominous.

Purpose: To report the case of a 34-week neonate who developed this rare condition and to discuss diagnostic and therapeutic measures.

Meningiomas of pineal region in children.

Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy.
