Background:
Extracranial meningiomas are common tumours but may occur in unexpected locations. Awareness can avoid misdiagnosis and inappropriate management of these tumours. We report the case of a 54-year-old Caucasian male with en plaque meningioma of the external ear canal and an intracranial temporal lobe meningioma.
Intervention:
The patient underwent extended canal wall down atticomastoidectomy with preservation of the ossicular chain and tympanic membrane and en bloc resection of the bony posterior canal wall, tumour, and overlying skin.
Results:
Radical removal of a grade I meningothelial meningioma was achieved. The tegmen tympani and dura were not breached. No connection with the temporal lobe meningioma was demonstrated. The patient recovered completely and experienced a marked improvement in hearing. No clinical signs of recurrent or residual tumour have occurred.
Conclusion:
Careful clinical examination and extensive radiological workup is required to avoid missing the unusual diagnosis of concurrent meningioma of the temporal bone and temporal lobe, and miss the chance to treat this disease adequately.
Insights
This case report highlights an unusual presentation of concurrent meningiomas in the external ear canal and temporal lobe. Early diagnosis and surgical intervention are crucial for successful treatment of these rare brain tumors.
Area of Science:
- Neurosurgery
- Otolaryngology
- Oncology
Background:
- Extracranial meningiomas, though common, can present in rare locations.
- Prompt recognition is vital to prevent misdiagnosis and ensure appropriate patient management.
Observation:
- A 54-year-old male presented with concurrent en plaque meningioma of the external ear canal and an intracranial temporal lobe meningioma.
- Surgical intervention involved an extended canal wall down atticomastoidectomy with tumor resection.
Findings:
- Complete resection of a grade I meningothelial meningioma was achieved without breaching the tegmen tympani or dura.
- The patient experienced full recovery with improved hearing and no signs of recurrence.
Implications:
- Concurrent meningiomas of the temporal bone and temporal lobe require thorough clinical and radiological evaluation.
- Accurate diagnosis is essential for effective treatment and management of these uncommon tumors.
