Summary
Intracranial lipomas are rare brain tumors. This case highlights successful surgical removal of a symptomatic quadrigeminal cistern lipoma causing obstructive hydrocephalus.
Area of Science:
- Neurology
- Neurosurgery
- Developmental Biology
Background:
- Intracranial lipomas are rare, benign congenital neoplasms, comprising 0.1-0.5% of primary brain tumors.
- Often associated with other cerebral developmental anomalies, they are typically slow-growing and asymptomatic.
Observation:
- A 37-year-old woman presented with symptoms of increased intracranial pressure.
- Imaging revealed a quadrigeminal cistern lipoma compressing the aqueduct of Sylvius, leading to obstructive hydrocephalus.
Findings:
- Surgical exploration identified a clear plane of cleavage, enabling complete resection of the lipoma.
- Post-surgery, the patient's initial symptoms resolved, though transient akinetic mutism occurred.
Implications:
- Symptomatic intracranial lipomas causing mass effect necessitate surgical intervention.
- Complete tumor removal is feasible and recommended only when a cleavage plane is evident, minimizing neurological damage.
