Occipital falcine meningioma presenting with ipsilateral hemifacial spasm: a case report
British Journal of Neurosurgery
|December 1, 1996
Abstract:
We report a large right occipital falcine meningioma, the main presenting feature of which was ipsilateral hemifacial spasm. The patient was relieved of the hemifacial spasm after the supratentorial tumour was resected. The pathogenesis of hemifacial spasm is reviewed in light of this unusual case and the treatment of hemifacial spasm secondary to a tumour is discussed.
Insights
A large brain tumor caused hemifacial spasm in a patient. Surgical removal of the occipital falcine meningioma resolved the spasm, highlighting tumor-induced facial nerve compression.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Hemifacial spasm (HFS) is an involuntary contraction of facial muscles.
- While often idiopathic or due to vascular compression, neoplastic causes are less common.
- Meningiomas, particularly falcine meningiomas, can present with atypical neurological symptoms.
Observation:
- A patient presented with a large right occipital falcine meningioma.
- The primary symptom was ipsilateral hemifacial spasm.
- The tumor was located in the supratentorial region.
Findings:
- Surgical resection of the supratentorial meningioma successfully relieved the patient's hemifacial spasm.
- This case suggests a direct causal link between the tumor mass and facial nerve irritation.
- Pathogenesis of tumor-induced HFS was explored.
Implications:
- Highlights the importance of considering intracranial tumors in the differential diagnosis of hemifacial spasm.
- Demonstrates the efficacy of surgical tumor removal in treating secondary HFS.
- Informs treatment strategies for rare cases of hemifacial spasm caused by meningiomas.
