5 Questions
Which of the following is NOT a cause of hydrocephalus?
Failure of CSF secretion
Where is CSF formed in the brain?
Choroid plexus
What is the normal rate of CSF production?
20 ml/h
What is the difference between obstructive and non-obstructive hydrocephalus?
Obstructive hydrocephalus is caused by obstruction to CSF flow, while non-obstructive hydrocephalus is caused by either obstruction to CSF flow outside the ventricles or failure of CSF absorption
What are the possible sites of obstruction in obstructive hydrocephalus?
Ventricles
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
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.
