Case Report


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.
