Which pathological condition is caused by excessive production of cerebrospinal fluid in the brain?

The condition characterized by excessive production of cerebrospinal fluid (CSF) in the brain is hydrocephalus. This condition occurs when the balance between the production and absorption of CSF is disrupted, leading to an accumulation of fluid within the ventricular system of the brain. As the fluid builds up, it can cause increased intracranial pressure, which may result in enlargement of the head in infants, neurological impairment, and other serious complications if left untreated.

Hydrocephalus can stem from various underlying issues, including congenital malformations, infection, or blockages in the CSF pathway. Understanding hydrocephalus is critical in surgical technology since it often requires interventions such as the placement of a shunt to help drain excess fluid and reduce pressure.

The other conditions listed do not pertain directly to the overproduction of CSF. Encephalocele refers to a defect in the skull that allows brain tissue to protrude, cranial bifida is associated with developmental anomalies of the spine and skull, and craniosynostosis involves the premature fusion of one or more cranial sutures, which can affect head shape but does not primarily relate to CSF production.
