We report a case of a 70-year-old woman with a BMI of 58 who developed cellulitis refractory to treatment, within an area of massive localized lymphedema. Biopsy showed angiosarcoma. MRI showed multiple lobulated, low T1, high T2 masses within a background of prominent soft tissue septal stranding, dilated lymphatic channels, and skin thickening. CT also showed the mass well, within the background lymphedema. Massive localized lymphedema is increasing in prevalence due to the worsening obesity epidemic. Radiologists should be aware that the presence of a nodule within an area of massive localized lymphedema is suspicious for sarcoma.

血管肉瘤产生于大量局部淋巴水肿。

我们报告了一例70岁的女性，其BMI为58，在局部局部淋巴水肿的区域发展为难治性蜂窝织炎。活检显示血管肉瘤。MRI显示，在突出的软组织间隔，淋巴管扩张和皮肤增厚的背景下，有多个小叶，低T1，高T2肿块。CT也显示肿块良好，在背景淋巴水肿内。由于肥胖病流行，大规模局部淋巴水肿的患病率正在增加。放射科医生应意识到，在局部局部淋巴水肿区域内有一个结节可疑为肉瘤。
