OBJECTIVE To describe the central nervous system (CNS) alterations present in a sample of oculo-auriculo-vertebral spectrum (OAVS) patients, trying to correlate them with other clinical features. METHOD Seventeen patients with diagnosis of OAVS were evaluated. All presented radiological evaluation of the CNS, normal GTG-Banding karyotype and clinical features involving at least two from the f...

PURPOSE In the older patient with dilated ventricles, it is often difficult to differentiate normal pressure hydrocephalus (NPH) from cerebral atrophy caused by Alzheimer disease (AD). This study was undertaken to see if dilatation of the perihippocampal fissures (PHFs) could be used as a distinguishing characteristic of these two disorders. METHODS MR images of 17 patients with AD were compa...

Hydrocephalus is a complex disorder of the formation, flow, and absorption cerebrospinal fluid (CSF), characterized by increased intracranial pressure, pathological dilatation cerebral ventricles, excessive accumulation CSF. This study describes correlation hydrocephalus degrees in children aged 0-12 with clinical manifestation through head CT scan to measure degree mild, moderate, severe using...

choroid plexus papillomas are rare intracranial tumors, accounting for less than 1% of all intracranial tumors in adults. however, they are relatively more common in children and constitute 1.5 to 4% of childhood intracranial tumors. in children, choroid plexus papillomas are predominately located in the lateral ventricles, followed by the forth and third ventricles and, rarely, in the cerebell...

Arterial blood entering the rigid skull is pulsatile. The brain requires a homeostatic environment, and a number of disease processes are now being linked to excessive pulsatility in the brain. Given this fact there must be some mechanism in normal brains for diverting the pulsatility away from the brain, providing a smooth flow of blood. Any such system would be constrained by the Monro-Kellie...

Hydrocephalus is a common brain disorder that is treated only with surgery. The basis for surgical treatment rests on the circulation theory. However, clinical and experimental data to substantiate circulation theory have remained inconclusive. In brain tissue and in the ventricles, we see that osmotic gradients drive water diffusion in water-permeable tissue. As the osmolarity of ventricular C...
