Metastasis to a spinal meningioma

BACKGROUND: Metastasis of one cancer to another is rare. Here, we report a spinal meningioma that was infiltrated by metastatic deposits from another cancer. CASE DESCRIPTION: A 62-year-old male presented with a progressive spastic paraparesis. Magnetic resonance (MR) imaging of the spine suggested a well-defined intradural extramedullary (IDEM) T8 mass in the dorsal spinal canal. When excised, it proved histologically to be a meningothelial meningioma infiltrated by metastatic deposits from an adenocarcinoma. CONCLUSION: Tumor to tumor metastasis rarely occurs, and meningioma, owing to its biological character and increased vascularity, is one of the most common recipients of a metastases from other lesions.
