Breast pseudoaneurysm: two case reports

Abstract

Breast pseudoaneurysm (PSA) is known as pulsatile or communicated hematoma or false aneurysm. The incidence is 0.05%-0.5%. PSA can be spontaneous or secondary to interventional breast procedures, surgery, penetrating chest trauma, local infection, and burns. Meanwhile, spontaneous PSAs occur in elderly patients, with atherosclerosis or with coagulation therapies. We present two cases of PSA, the first case is a 29-years-old female and a 49-years-old female, who came for a check-up due to a recent a pulsatile mass after a breast core needle biopsy. Faced at hypoechoic mass is important to use color Doppler to rule out the diagnosis of PSA. Because of the low incidence, guidelines for treatment or a standard conduct are not established. However, it is important to set up management in order to avoid further complications.
