Background
Currently, due to the widespread use of mammography for screening, the frequency of lesions that require histological diagnosis, palpable or non-palpable lesions has increased. Ultrasonography (US) guided biopsies are used as an important alternative to open surgical biopsies in the diagnosis of non-palpable lesions(1). 14-G long-throw needles are the standard. Core biopsies provide a more accurate diagnosis than fine needle aspirations(1). The sensitivity of US-guided core biopsy is reported to be between 92% and 100% (Avg. 96%)(1). Core biopsies provide pathologic diagnosis as well as prognostic information to determine primary systemic treatment.
The incidence of complications in 14-G core needle breast biopsies is lower than open surgical biopsies. The use of ultrasound as a guide allows monitoring of complications during the procedure(2). The most common complication is hematoma development(3). Other possible complications are ecchymosis, pseudoaneurysm formation, pneumothorax, implant rupture and infection.
The development of pseudoaneurysm in the breast after core biopsy has been described in the literature and surgical treatment requirement has been reported in most patients(3).
We presented two cases with pseudoaneurysm which was arised after ultrasound-guided core needle breast biopsy.
