Summary
Metastatic meningioma, though rare, can occur in recurrent or malignant cases. This report details the first isolated chest wall metastasis, highlighting diagnostic challenges and the potential benefit of surgical resection.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Meningiomas are typically benign tumors, but a subset can metastasize.
- Management strategies for metastatic meningiomas remain undefined.
- Recurrent or malignant meningiomas have a higher propensity for metastasis.
Observation:
- A 64-year-old woman presented with an isolated left chest wall mass 13 years after initial meningioma resection and subsequent recurrence treatment.
- Imaging revealed a destructive lesion of the ninth rib with subpleural extension.
- Initial diagnosis was soft-tissue sarcoma, but pathology confirmed metastatic meningioma.
Findings:
- This case represents the first documented instance of meningioma metastasis presenting solely in the chest wall.
- Diagnostic confirmation required advanced techniques, including electron microscopy and immunohistochemistry.
- The patient underwent successful resection and adjuvant radiation therapy.
Implications:
- Accurate diagnosis of metastatic meningioma can be challenging, necessitating consideration in patients with a history of the disease.
- Isolated metastases may warrant aggressive management, including surgical resection.
- This case expands the understanding of meningioma metastatic patterns and treatment possibilities.
