Question

Quizplus · Accepted Answer

Noncommunicating hydrocephalus occurs when there is an obstruction present in the aqueduct of Sylvius or other channels, preventing the normal flow of cerebrospinal fluid (CSF) out of the ventricles. This obstruction can be caused by various factors, such as a tumor or a congenital abnormality. As a result, excess CSF accumulates in the ventricles, leading to hydrocephalus.
