We describe a malignant granular cell tumor in the semimembranosus muscle of a 61-year-old woman. Magnetic resonance images disclosed a tumor with intermediate and low signal intensity on both T1- and T2-weighted images, measuring about 7 x 4 x 4 cm in size. The patient showed an uneventful clinical course during a 30-month follow-up period after the wide excision. The pertinent findings in making the diagnosis of malignant granular cell tumor are large size, intramuscular location, and mitosis including an atypical mitosis.
我们描述了一名61岁女性半膜肌中的恶性颗粒细胞瘤。磁共振成像显示，该肿瘤在T1加权和T2加权图像上均呈中等和低信号强度，大小约为7×4×4厘米。在广泛切除后的30个月随访期内，患者临床过程平稳。诊断恶性颗粒细胞瘤的相关发现包括肿瘤体积大、位于肌肉内以及存在有丝分裂，包括非典型有丝分裂。
