Summary
Intracranial epidermoid tumors, rare ectodermal lesions, can occur in the third ventricle. This case highlights surgical removal of a third ventricle epidermoid tumor, a location with limited reported instances.
Area of Science:
- Neurosurgery
- Neuropathology
- Oncology
Background:
- Intracranial epidermoid tumors are rare, accounting for 1% of all brain tumors.
- They typically arise from ectodermal remnants and commonly occur in the cerebellopontine angle or chiasmal regions.
Observation:
- A case of a third ventricle epidermoid tumor in a 68-year-old woman presenting with headaches and nausea.
- CT revealed a hypodense mass with hydrocephalus; MRI showed characteristic signal intensities.
- The tumor was surgically resected via a transcallosal approach.
Findings:
- This report details a rare instance of an intracranial epidermoid tumor located within the third ventricle.
- Surgical removal using an ultrasonic aspirator was successful.
- Literature review identified only 8 previously reported cases of third ventricle epidermoid tumors.
Implications:
- This case expands the known anatomical distribution of intracranial epidermoid tumors.
- Highlights the importance of considering rare tumor locations in differential diagnoses.
- Contributes to the limited case series for this specific tumor location, aiding future management strategies.
