Summary
This study details a rare case of bilateral intratentorial lipomas encasing the trigeminal nerve. The findings offer insights into the developmental origins of intracranial lipomas.
Area of Science:
- Neuroscience
- Neurosurgery
- Pathology
Background:
- Intracranial lipomas are rare congenital tumors.
- Their occurrence in the cerebellopontine angle and Meckel's caves is exceptionally uncommon.
Observation:
- A unique case of bilateral intratentorial lipomas extending into Meckel's caves and cerebellopontine angle is presented.
- Surgical and histopathological analysis confirmed lipoma encasement of the trigeminal nerve within Meckel's caves.
Findings:
- The lipomas originated from the anteromedial margins of the tentorium cerebelli.
- This anatomical origin supports a proposed theory for intracranial lipoma development.
Implications:
- This case expands the understanding of rare intracranial lipoma presentations.
- It provides valuable data for theories on the embryological development of these tumors.
