What does hydrocephalus involve?

1. Abnormal accumulation of fluid in the cranial vault

2. Increased intracranial pressure

3. Damage to the spinal cord

4. Development of cysts in the brain

The correct answer is: Abnormal accumulation of fluid in the cranial vault

Hydrocephalus specifically refers to the abnormal accumulation of cerebrospinal fluid (CSF) within the cranial vault, which is the space inside the skull. This condition can lead to a range of complications due to the increased volume of fluid, including increased pressure on the brain structures. While increased intracranial pressure is a consequence of hydrocephalus, it is not the defining characteristic of the condition itself; rather, it is a result of the accumulation of fluid. Damage to the spinal cord and the development of cysts in the brain do not characterize hydrocephalus. Instead, these issues may arise from other neurological disorders or injuries. Understanding hydrocephalus as primarily focused on the accumulation of fluid helps clarify its distinct nature in the field of neurology and its implications for treatment and management.
