ventricular system
Network of fluid-filled cavities within the brain where cerebrospinal fluid is produced and circulates.
Full Definition
The ventricular system consists of four interconnected cavities (lateral, third, and fourth ventricles) within the brain that produce and circulate cerebrospinal fluid. In neurosurgical oncology, tumors can obstruct these pathways causing hydrocephalus, or arise from ventricular walls (intraventricular tumors). Understanding ventricular anatomy is crucial for surgical planning and assessing tumor location relative to CSF flow patterns.
Usage
Usage note: Always singular when referring to the complete system; plural 'ventricles' when referring to individual chambers.
