隆突性纤维皮肤肉瘤1例MRI分析

MRI Analysis of One Case of Dermatofibrosarcoma Protuberans

报道1例确诊的隆突性纤维皮肤肉瘤(DFSP)患者的MRI表现。患者青年男性,半年前发现右大腿皮肤肿物,近期自觉肿物增大明显;磁共振示:右股部皮下软组织椭圆形长T1、FS-T2高信号影,DWI信号增高,ADC信号减低,ADC值约0.8×10^(-3)mm^(2)/s。

We report the MRI presentation of a patient with a confirmed dermatofibrosarcoma protuberans(DFSP).The patient,a young male,was found to have a skin swelling on his right thigh six months ago,initially about the size of peanut rice.Recently,he felt that the swelling had increased significantly,with no pain,no numbness,no high skin temperature,and no rupture;MRI showed an elliptical long T1 and FS-T2 high signal shadow in the subcutaneous soft tissue of the right femur,with local ectopia,increased DWI signal,decreased ADC signal,and ADC value of about 0.8×10^(-3)mm^(2)/s.
