Background and Aim: Ventriculoperitoneal shunt (VPS) is the most commonly used procedure for treatment of hydrocephalus in children. Abdominal cerebrospinal fluid pseudocyst is a rare complication but potentially fatal. The pathogenesis of this complication remains unclear. This complication should be considered during differential diagnosis of an abdominal mass. Our aim is to report how large ...

A xenon-133 method was used to measure cerebral blood flow (CBF) before and after cerebrospinal fluid (CSF) removal in patients with normal pressure hydrocephalus (NPH). Preliminary results suggested that shunting should be performed on patients whose CBF increased after CSF removal. There was a significant increase in CBF in patients with NPH, which was confirmed by the favorable outcome of 88...

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a disorder of elevated intracranial pressure of unknown cause. Patients present with daily headache, pulse-synchronous tinnitus, transient visual obscurations, papilledema with its associated visual loss, and diplopia from sixth nerve paresis. Many disease associations have been alleged, but few besides obesity, h...

Introduction: There are several options for cerebrospinal fluid diversion in patients with normal pressure hydrocephalus. Fixed and programmable valves, with or without anti-siphon devices, have been used for ventriculoperitoneal shunts and horizontal-vertical valves for lumboperitoneal shunts. Recently, a horizontal-vertical valve was developed for ventriculoperitoneal shunts and has been demo...

Normocephalic children found to have ventriculomegaly during evaluation of long-standing (4.5-8.5 years) neurological disorder were tested for academic achievement, intellectual quotient and neuropsychological functioning. Radioactive iodinated serum cisternography, pre and post-shunt electrophysiological studies (visual evoked responses, brainstem auditory evoked potentials, sleep electroencep...

Cerebrospinal fluid (CSF) overproduction results from either CSF infection or choroid plexus hypertrophy or tumor, with only a single idiopathic case described so far. We report a unique case of a male infant with Crouzon syndrome who presented with intracranial hypertension, caused by up to 4-fold increase in CSF daily production. Conditions related to CSF overproduction, namely central nervou...
