hydrocephalus
Pronunciation: /ˌhaɪdroʊˈsɛfələs/
Abnormal accumulation of cerebrospinal fluid within the brain's ventricular system causing ventricular enlargement.
Full Definition
Hydrocephalus is a neurological condition characterized by the abnormal accumulation of cerebrospinal fluid (CSF) within the ventricular system of the brain, resulting in ventricular dilatation. This can occur due to overproduction of CSF, obstruction of CSF flow, or impaired CSF absorption. Hydrocephalus may be congenital or acquired and can present as communicating (normal pressure) or non-communicating (obstructive) forms. The condition requires prompt recognition and treatment, often involving surgical intervention such as shunt placement or endoscopic third ventriculostomy. Neuroimaging plays a crucial role in diagnosis and monitoring of treatment response.
Usage
Usage note: Do not hyphenate; distinguish from simple ventriculomegaly in clinical contexts.
