摘要
本病例是一名四十岁的无症状女性,无个人或家族乳腺癌病史,在乳房 X 光筛查中发现右侧乳房有局灶性不对称,随后接受了核心针活检(CNB)。八个月后,她在乳腺超声波检查中发现了一个突出的邻近血管结构,并伴有圆形外囊,证实为活检后假性动脉瘤。乳腺假性动脉瘤虽然极为罕见,但却是在核心针活检过程中不慎刺穿血管造成的,尤其是在使用较大规格的针头时。乳房假性动脉瘤表现为乳房内可触及的搏动性肿块,是界限清晰的异质结构,在彩色多普勒成像中表现为进血动脉的湍流。在多普勒超声检查中,这种显示往返波形的漩涡征也被称为 "阴阳 "征。乳腺核芯穿刺活检后假性动脉瘤虽然罕见,但应被视为核芯穿刺活检后的潜在并发症。了解假性动脉瘤的影像学特征、风险因素和可用的治疗方案对于早期诊断和适当治疗至关重要。本病例强调了在活检过程中保持警惕的重要性,以及在出现此类并发症时及时识别和干预的必要性。
Pseudoaneurysm in the Axillary Tail of the Breast After A Core Needle Biopsy.
We present the case of a forty-year-old asymptomatic female with no personal or family history of breast cancer, who underwent a core needle biopsy (CNB) following the identification of a focal asymmetry in the right breast on screening mammography. Eight months later, a prominent adjacent vascular structure with a round outpouching was detected on breast ultrasound, confirmed as a post-biopsy pseudoaneurysm. Breast pseudoaneurysms, although exceedingly rare, result from inadvertent vessel puncture during core needle biopsies, particularly when larger gauge needles are used. They present as palpable, throbbing lumps in the breast and are well-defined heterogeneous structures that exhibit turbulent flow with a feeding artery on color Doppler imaging. This swirling sign showing a to-and-fro waveform is also known as the "yin-yang" sign on Doppler ultrasound. Post-CNB pseudoaneurysms in the breast, while rare, should be considered as potential complications following core need biopsy. Understanding their characteristic imaging features, risk factors, and available management options is essential for early diagnosis and appropriate treatment. This case underscores the importance of vigilance in biopsy procedures and the need for prompt recognition and intervention in case of such complications.
