How does subarachnoid hemorrhage cause communicating hydrocephalus?
A) By obstructing the cerebrospinal fluid flow between the ventricles
B) By increasing the cerebrospinal fluid secretion into the subarachnoid space
C) By impairing blood flow to the arachnoid villi
D) By obstructing the absorption of cerebrospinal fluid by the arachnoid villi

Question

Quizplus · Accepted Answer

Subarachnoid hemorrhage can cause communicating hydrocephalus by obstructing the absorption of cerebrospinal fluid by the arachnoid villi. The presence of blood in the subarachnoid space can clog the arachnoid villi, which are responsible for draining the cerebrospinal fluid from the subarachnoid space into the bloodstream. This impairs the normal absorption of cerebrospinal fluid, leading to an accumulation of fluid and the development of hydrocephalus.
