Radiation-Associated Angiosarcoma of the Breast: What the Radiologist Needs to Know.

ABSTRACT

OBJECTIVE: The purpose of this article is to describe the diagnosis, treatment, and follow-up of radiation-associated angiosarcoma (RAS) of the breast. CONCLUSION: Radiologists play an important role in the diagnosis of RAS, which may initially present clinically as erythema, ecchymosis, or skin thickening. Conventional imaging with mammography and ultrasound is less sensitive than MRI for the diagnosis of RAS. Follow-up CT is important to monitor treatment response.
