Malignant fibrous histiocytoma (MFH) arising from the renal capsule is a rare tumor. We report a case of 55-year-old man with this tumor. Radiological imaging, including magnetic resonance (MR) imaging, was helpful in the differential diagnosis between MFH of the renal capsule and other renal tumors. In particular, a hypo-intense area identified on T(2)-weighted images reflecting the fibrous component was identified as an important characteristic of renal MFH.
起源于肾包膜的恶性纤维组织细胞瘤（MFH）是一种罕见的肿瘤。我们报告一例55岁男性患有此肿瘤的病例。包括磁共振（MR）成像在内的放射学成像有助于肾包膜MFH与其他肾肿瘤之间的鉴别诊断。特别是，在T2加权图像上发现的反映纤维成分的低信号区被确定为肾MFH的一个重要特征。
