【摘要】：正患者女,51岁,无意中发现右前臂肿物15天,余无不适。MRI表现:右前臂中段拇长屈肌内可见椭圆形异常信号,大小约18 mm×16 mm×38 mm。与肌肉组织相比,T_1WI、T_2WI及抑脂T_2WI呈等信号,信号不均匀,T_2WI及抑脂T_2WI可见斑片状高信号,病灶边界不清,周围见斑片状抑脂高信号(图1~4)。增强后,病变呈渐进性强化,强化不均匀,病灶边缘强化相对明显(图5~7),动态增强曲线呈缓
[Abstract]:The patient was 51 years old and found the tumor of the right forearm for 15 days. There was no discomfort. MRI: oval abnormal signal could be seen in the flexor pollicis longus muscle of the right forearm. The size was about 18 mm 脳 16 mm 脳 38 mm. Compared with the muscle tissue, the signal intensity of T _ (1) W _ (I) T _ (2WI) and T _ (2) T _ (2WI) were different and the signal intensity was uneven. Plaque hyperintensity was observed on T2WI and lipid-suppressive T2WI, the boundary of lesion was unclear, and the signal intensity of hyperlipidemic plaque was observed around the lesion (Fig. 1 / 4). After enhancement, the lesions showed progressive enhancement and uneven enhancement. The edge enhancement of the lesion was relatively obvious (Fig. 5, 7), and the dynamic enhancement curve was slow.
