Study Notes
Hydrocephalus Causes
- NOT a cause of hydrocephalus: question needs to be answered by a specific option or text
Cerebrospinal Fluid (CSF) Formation
- CSF is formed in the choroid plexus of the brain
CSF Production
- Normal rate of CSF production: 500-600 mL/day
Hydrocephalus Types
- Obstructive hydrocephalus: occurs when there is a blockage in the flow of CSF, typically in the ventricles or aqueducts
- Non-obstructive hydrocephalus: occurs when there is an imbalance between CSF production and absorption
Obstructive Hydrocephalus Obstruction Sites
- Possible sites of obstruction in obstructive hydrocephalus: aqueduct of Sylvius, foramina of Luschka and Magendie, and the cerebral aqueduct

Description
Test your knowledge on hydrocephalus, a condition characterized by abnormal enlargement of the ventricles due to excessive accumulation of cerebrospinal fluid (CSF). This quiz covers the causes, symptoms, and treatment options for hydrocephalus.
