OBJECT Communicating hydrocephalus is an uncommon complication in patients treated for glioblastoma multiforme (GBM). Its pathogenesis remains unclear. The authors evaluated the clinical and radiological factors associated with the onset of communicating hydrocephalus and the impact of ventriculoperitoneal (VP) shunt surgery on the outcome of these patients. METHODS One hundred twenty-four pa...
Extra-axial fluid collections following decompressive craniectomy have been observed in a variety of patient populations. These collections have traditionally been thought to represent extra-axial signs of hydrocephalus, but they often occur even in settings where hydrocephalus has been optimally treated. This study aims to elucidate the phenomenon of extra-axial fluid collections after decompr...
Previous studies demonstrated that thrombin is an important factor in brain injury after intracerebral hemorrhage. This study investigated the effect of thrombin on hydrocephalus development in a rat intraventricular hemorrhage (IVH) model. There were three parts in this study. First, male Sprague-Dawley rats had an injection of 200 μL saline, autologous blood or heparinized blood, into the rig...
BACKGROUND AND PURPOSE MR imaging is used in the diagnostic evaluation of patients with idiopathic normal pressure hydrocephalus. The aim of this study was to describe the prevalence of several imaging features and their prognostic use in the selection of shunt candidates with idiopathic normal pressure hydrocephalus. MATERIALS AND METHODS Preoperative MR imaging scans of the brain were retro...
Bilateral papilledema secondary to obstructive or communicating hydrocephalus in patients with vestibular schwannomas is a known presentation; however, papilledema in the absence of hydrocephalus is rarely reported and its mechanism is poorly understood. We report a case of a 20-year-old woman presenting with visual deterioration and bilateral papilledema on fundoscopy. Magnetic resonance imagi...
The ventricle-to-background ratio and clearance rate constant measured by indium-111 diethylenetriaminepenta-acetic acid single photon emission computed tomography ((111)In-DTPA SPECT) were evaluated for predicting hydrocephalus in 16 patients at 2 to 3 weeks after onset of subarachnoid hemorrhage. The activity in the lateral ventricles, basal cistern, and hemispheric convexities was measured a...
The entrapment of intracranial air from the check valve system results in a tension pneumocephalus. It should be distinguished from simple pneumocephalus because they are intracranial space-occupying masses that can threaten life. Communicating hydrocephalus is a serious and frequent complication of post-traumatic head injury. Head injury is one of the most common causes in etiopathogenesis of ...
To determine the strength and nature of the association between hydrocephalus and hyperactivity and to test the dual pathway model (DPM) of AD/HD, we compared a group of 51 children and adolescents with hydrocephalus with 57 normally developing controls from the general population on a battery of neuropsychological assessments. The mean hyperactivity scores were significantly greater in the gro...
Shunt placement was a standard treatment for patients with hydrocephalus. It is indicated for both communicating and noncommunicating types of hydrocephalus and for various etiologies of hydrocephalus, including infection; congenital malformations, such as aqueductal stenosis, congenital cysts, mega cisterna magna, and Arnold-Chiari malformation; hemorrhage; and tumor. The risk of shunt malfunc...
