Summary
Intratumoural bleeding into trigeminal neurinomas is rare, presenting acutely. This case highlights hemorrhage within a large trigeminal neurinoma causing sudden ptosis, hemifacial pain, and sensory loss.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Trigeminal neurinomas are benign tumors arising from the trigeminal nerve.
- Intratumoural hemorrhage is an uncommon complication of these tumors.
Observation:
- A rare case of intratumoural bleeding into a large trigeminal neurinoma is presented.
- The patient experienced an apoplectic onset with persistent unilateral ptosis, hemifacial pain, and sensory loss.
Findings:
- The clinical presentation was directly attributed to a hemorrhage within the trigeminal neurinoma.
- This event led to acute neurological deficits affecting the trigeminal nerve distribution.
Implications:
- Highlights the potential for sudden, severe neurological deficits due to hemorrhage in trigeminal neurinomas.
- Emphasizes the importance of considering intratumoural bleeding in the differential diagnosis of acute neurological presentations involving the trigeminal nerve.
- Suggests prompt neuroimaging for diagnosis and management planning.
