Epidermoid tumor presenting as painful tic convulsif
Surgical Neurology
|March 1, 1983
Summary
Surgical removal of a cerebellopontine angle epidermoid tumor relieved a patient's left-sided hemifacial spasm and trigeminal neuralgia. Symptoms significantly improved post-operation, indicating the tumor was the cause.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Epidermoid tumors are congenital tumors that can cause neurological symptoms due to mass effect.
- Hemifacial spasm and trigeminal neuralgia are common neurological disorders that can be caused by tumors compressing cranial nerves.
Observation:
- A 49-year-old male presented with left-sided hemifacial spasm and ipsilateral trigeminal neuralgia.
- Computed tomography (CT) scan with metrizamide enhancement revealed a cerebellopontine angle epidermoid tumor.
Findings:
- Complete surgical resection of the epidermoid tumor was performed.
- Post-operatively, the patient experienced complete relief from trigeminal neuralgia (facial pain).
- Hemifacial spasm showed significant improvement, with a decreased frequency of spasms.
Implications:
- Surgical removal of cerebellopontine angle epidermoid tumors can effectively treat associated neurological symptoms.
- Early diagnosis and surgical intervention are crucial for managing symptomatic epidermoid tumors.
- This case highlights the importance of neuroimaging in identifying the cause of cranial nerve compression syndromes.
