A 70-year-old woman presented with mild left hemiparesis and intermittent global headache. Magnetic resonance imaging showed a 6 x 6 x 6-cm tumor in the right frontal lobe, and abdominal computed tomography revealed a 8 x 8 x 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.
一名70岁女性出现轻度左侧偏瘫和间歇性全头痛。磁共振成像显示右额叶有一个6×6×6厘米的肿瘤，腹部计算机断层扫描显示左肾有一个8×8×7厘米的肿块病变。磁共振成像显示脑肿瘤由中央高信号囊性成分和外周低信号成分组成。患者接受了颅内肿块的全手术切除。组织学和免疫组化检查显示该病变为伴有转移性肾细胞癌的脂肪瘤样脑膜瘤。这两种肿瘤都很罕见。磁共振成像结果提示但并非特异性地提示伴有转移瘤的脑膜瘤。
