Summary
This case report details a rare extracranial fibrous meningioma (WHO Grade 1) presenting as a temporal swelling. Surgical debulking was partially successful, with residual tumor requiring further management.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Meningiomas are typically intracranial tumors.
- Extracranial meningiomas are rare and can present with varied clinical and imaging features.
- This case focuses on an unusual presentation of a fibrous meningioma.
Observation:
- A 46-year-old male presented with painless, recurrent bilateral ear discharge and a growing right temporal swelling.
- Imaging revealed a right infratemporal soft tissue mass involving the temporalis muscle with an intradural component and sphenoid bone hyperostosis.
- Intraoperative findings confirmed tumor invasion of the temporalis muscle.
Findings:
- Histopathology confirmed a fibrous meningioma, WHO Grade 1.
- Surgical debulking of the temporalis tumor was performed, with tumor involving resection margins.
- Follow-up MRI showed a residual extracranial component, necessitating further surgical planning.
Implications:
- This case underscores the importance of considering meningioma in the differential diagnosis of extracranial temporal masses.
- It highlights the diverse presentations and management challenges of extracranial meningiomas.
- Further investigation into the optimal management strategies for residual extracranial meningiomas is warranted.
