A 70-year-old woman presented with mild left hemiparesis and intermittent global headache. Magnetic resonance imaging showed a 6 × 6 × 6-cm tumor in the right frontal lobe, and abdominal computed tomography revealed a 8 × 8 × 7-cm mass lesion in the left kidney. Magnetic resonance imaging showed that the brain tumor consisted of a central hyperintense cystic component and an outer hypointense component. The patient underwent total surgical excision of the intracranial mass. Histological and immunohistochemical examination showed that the lesion was a lipomatous meningioma harboring metastatic renal-cell carcinoma. Both of these tumors are rare. The magnetic resonance imaging findings are indicative of but not specific to meningioma harboring metastatic tumor.
- Lipomatous meningioma
- Renal-cell carcinoma
