Initially, the patient had noticed a painless swelling of the left arm for which he had an MRI (the advanced diagnoses were soft tissue sarcoma/angiosarcoma of the basilic vein) and chest/abdominopelvic CT was unremarkable. After complete surgical resection and histopathological analysis, the diagnosis was angiosarcoma.

6 months after surgery, another mass appeared in the right arm which has approximately the same location and MRI appearance. The chest/abdominopelvic CT was also unremarkable. After surgical resection with histopathological exam, the diagnosis was also angiosarcoma.
