Summary
This case report details a rare supratentorial ependymoma in a young male. A contralateral transfalcine interhemispheric approach enabled complete microsurgical removal of the brain tumor.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Extraventricular supratentorial ependymomas are rare, often lacking continuity with the ventricular system.
- Most ependymomas occur infratentorially or intraventricularly.
Observation:
- A 16-year-old male presented with a large (40x50x60 mm) solid-cystic lesion between the left superior frontal-cingulate gyri.
- The lesion was surgically removed via a contralateral transfalcine interhemispheric approach.
Findings:
- Histopathology confirmed a World Health Organization (WHO) Grade II ependymoma.
- The surgical approach facilitated total tumor resection.
Implications:
- The contralateral transfalcine interhemispheric approach is a viable corridor for supratentorial ependymomas.
- This technique offers an adequate working angle with minimal brain manipulation, favoring complete resection.
