Which statement about hydrocephalus in spina bifida is correct?

• A. It does not require monitoring after treatment
• B. It commonly resolves without any intervention
• C. It often requires a shunt to divert CSF
• D. It is unrelated to brain anomalies

Answer: (C)

Hydrocephalus in spina bifida commonly arises from disrupted CSF dynamics due to hindbrain malformation, which leads to ventricular enlargement and increased intracranial pressure. Because this buildup of CSF can continue to harm brain development and function, many cases require diversion of CSF with a shunt, typically a ventriculoperitoneal system, to drain the excess fluid and reduce pressure. After treatment, ongoing monitoring is essential because shunt-related issues such as malfunction, overdrainage, or infection can occur and may need revision. Spontaneous resolution is not typical, and this condition is linked to brain anomalies associated with spina bifida, not unrelated to brain structure.
