hydrocephalus
Pronunciation: hahy-druh-SEF-uh-luhs
Abnormal accumulation of cerebrospinal fluid within the brain ventricles, requiring neurosurgical intervention in neonates.
Full Definition
Hydrocephalus is a condition characterized by excessive accumulation of cerebrospinal fluid (CSF) within the ventricular system of the brain, leading to increased intracranial pressure. In neonates, it often occurs secondary to intraventricular hemorrhage or congenital malformations. The condition requires careful monitoring of head circumference and may necessitate surgical placement of a ventriculoperitoneal shunt. Early detection and treatment are crucial to prevent developmental delays and neurological complications.
Usage
Usage note: Often abbreviated as HC in clinical notes; distinguish from simple ventriculomegaly which may be transient.
