The term hydrocephalus is derived from two words: "hydro," meaning water, and "cephalus," referring to the head. At the time the article was created Frank Gaillard had no recorded disclosures. Axial T2 (B) and FLAIR (C) plus coronal short T inversion recovery (D) images demonstrate linear cortical veins (arrows) traversing the enlarged extracerebral spaces that conform to CSF intensities on all sequences. Ventricle are normal in size: Our data suggest that MRI-detected CSF space enlargement may be of. Untreated, symptomatic arachnoid cysts can lead to permanent brain damage, severe pain, movement disorders and serious health problems. b Corresponding axial T2-weighted image shows prominent extra-axial space (asterisks). {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Hacking C, Thurston M, et al.

A 56-year-old man was brought to our hospital by his family, seeking medical treatment for the patients long-standing progressive word-finding difficulties, forgetfulness, agitation and social withdrawal. CSF is of lower density than the grey or white matter of the brain, and therefore appears darker on CT images. Extra-axial cerebrospinal fluid in high-risk and normal-risk children From 4th ventricle some CSF trickles down to central canal of spinal cord. It consists of a long, flexible tube with a valve that keeps fluid from the brain flowing in the right direction and at the proper rate. The symptoms are usually vague. "Ventricular enlargement reflects changes in both the white matter and gray matter of the brain and can be caused by both cerebrovascular disease and Alzheimer's disease," said Erten-Lyons.

Get useful, helpful and relevant health + wellness information. Some congenital causes include achondroplasia due to narrow foramen magnum and jugular foramina. The most prominent enlarged spaces were 3-cm-sized lesions of the petrous apices that were considered to be PACs because of their having CSF intensity that was contiguous with CSF within the Meckel cave. 2000 Oct;33(4):188-93. doi: 10.1159/000055951. HHS Vulnerability Disclosure, Help It should be suspected if the collection thickness is wider than 6 mm, shows higher T2 fluid-attenuated inversion recovery (FLAIR) signal as compared to cerebrospinal fluid (CSF), and displays hemorrhagic staining on T2*GRE. The gait in many patients with NPH is very distinctive: wide-based, short, slow and shuffling. No change was seen on serial exami nation and, thus, we concluded that the hyperdensity rep resents the normal falx.
