The purpose of this exhibit is: The objective of this paper is to describe the clinical and imaging features of cavernous hemangiomas, emphasizing those that allow it to differentiate themselves from angiosarcoma and other breast lesions. The major teaching points of this exhibit are: 1 - Nodules of solid appearance, usually hypo or hyperechoic and slightly heterogeneous. 2 - Classified as cavernous and capillary depending on the size of the vessels. Mixed are more common than pure capillaries. 3 - Usually are extraparenchymal (subcutaneous tissue) while angiosarcomas usually are intraparenchymal. 4 - Unlike angiosarcoma, hemangioma show no flow on color doppler study. The flow inside the vascular structures is too slow to be demonstrated. 5-In mammograms, appears as a circumscribed, round, oval or lobulated, well-defined and high density lesion.    

Cavernous hemangiomas are benign vascular tumors, usually located in the subcutaneous tissue. Classically, the diagnosis of cavernous hemangioma in adults was percutaneous biopsy, since it could be mistaken for a low-grade angiosarcoma (malignant lesion). However, there are imaging features of cavernous hemangiomas that allow us to differentiate them from angiosarcomas, avoiding unnecessary biopsies.
