Abstract:
Extracranial meningiomas of the head and neck region are very rare, although secondary extracranial meningiomas beside meningiomas of primary extracranial origin have also been described. Trauma, radiation and (uncommonly) metastatic spread have been associated with the pathogenesis of secondary extracranial meningiomas. We present a case of a 53-year-old patient who required six neurosurgical interventions because of a recurrent intracranial meningioma. Further surgery was required for tumor in the left parotid gland. Histological examination of this neoplasm showed an atypical meningotheliomatous meningioma. The patient is now 17 months after surgery and is free of local recurrences or metastases.
Insights
Extracranial meningiomas are rare head and neck tumors. This case highlights a secondary extracranial meningioma in the parotid gland following multiple intracranial surgeries, with no recurrence after treatment.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Extracranial meningiomas are uncommon tumors, with secondary forms potentially linked to trauma or prior radiation.
- Recurrent intracranial meningiomas can rarely lead to secondary extracranial involvement.
Observation:
- A 53-year-old patient underwent six neurosurgical procedures for a recurrent intracranial meningioma.
- Subsequent surgery was necessary to address a tumor in the left parotid gland.
Findings:
- Histological examination revealed an atypical meningotheliomatous meningioma in the parotid gland.
- The patient remained disease-free with no local recurrence or metastases 17 months post-surgery.
Implications:
- This case underscores the possibility of secondary extracranial extension of meningiomas, even in rare locations like the parotid gland.
- It emphasizes the importance of thorough histopathological evaluation and long-term follow-up for complex meningioma cases.
