Radiation-associated angiosarcoma of the breast (RAASB) is a rare and aggressive malignancy occurring after radiation therapy as part of breast cancer treatment. RAASB usually presents several years after prior radiation and typically involves the skin with or without involvement of the parenchyma. Most RAASB are detected as cutaneous changes on physical exam. Herein, we present a unique case of a clinically occult RAASB diagnosed as non-mass enhancement on annual surveillance breast MRI.
乳腺放疗相关血管肉瘤（RAASB）是一种罕见且侵袭性强的恶性肿瘤，发生于乳腺癌治疗的放疗之后。RAASB通常在既往放疗数年之后出现，典型表现为累及皮肤，可伴有或不伴有实质受累。多数RAASB通过体格检查发现皮肤改变得以确诊。在此，我们报告一例独特的临床隐匿性RAASB病例，该病例在年度乳腺MRI筛查时被诊断为非肿块强化。
