The perivascular epithelioid cell tumor (PEComa) is a neoplasm composed primarily of HMB-45-positive epithelioid cells with a perivascular distribution. Both benign and malignant PEComas have been reported in diverse anatomic locations. We report the MRI features of a metastatic PEComa to the liver that originated within a renal angiomyolipoma (AML).
血管周上皮样细胞瘤（PEComa）是一种主要由HMB-45阳性上皮样细胞组成且呈血管周分布的肿瘤。良性和恶性PEComa均已在不同解剖部位有报道。我们报告了一例起源于肾血管平滑肌脂肪瘤（AML）的肝转移性PEComa的MRI特征。
