Summary
Prolactinomas, common pituitary tumors, can rarely cause hydrocephalus. This case report details a rare instance of a prolactinoma presenting with hydrocephalus in an elderly woman.
Area of Science:
- Neuroendocrinology
- Neurosurgery
Background:
- Prolactinomas are the most frequent pituitary adenomas, typically causing hormonal imbalances or visual disturbances due to optic chiasm compression.
- Pituitary adenomas presenting with hydrocephalus are exceptionally rare, with only three prior documented cases.
Observation:
- An 81-year-old female patient presented with a pituitary adenoma causing hydrocephalus.
- This presentation is highly unusual for pituitary adenomas.
Findings:
- The case highlights a rare manifestation of prolactinomas.
- The study reviews existing literature on pituitary adenomas associated with hydrocephalus.
Implications:
- This case expands the known clinical spectrum of prolactinomas.
- Understanding rare presentations is crucial for diagnosis and management of pituitary tumors.
