Pseudoaneurysm of the breast is a rare complication following large core needle biopsy. Persistent vascularized lesions after hematoma regression suggest this diagnosis, treatable with endovascular or surgical methods.
Area of Science:
- Radiology
- Vascular Surgery
- Oncology
Background:
- Pseudoaneurysm of the breast is an infrequent complication associated with large core needle biopsy.
- This case highlights a pseudoaneurysm developing after a breast mass biopsy.
Observation:
- A patient developed an extensive hematoma post-core needle biopsy.
- While the hematoma regressed, a persistent nodular area was noted.
- Ultrasonography and magnetic resonance imaging confirmed a pseudoaneurysm.
Findings:
- Extensive breast hematomas from core needle biopsies typically resolve within weeks.
- Persistent vascularized lesions on ultrasound warrant consideration for pseudoaneurysm.
- Diagnosis was confirmed through imaging modalities.
Implications:
- Early recognition of persistent vascularized lesions is crucial for diagnosing breast pseudoaneurysm.
- Management options include endovascular procedures or surgical resection.
- This emphasizes the importance of vigilant follow-up after breast biopsies.

The Mammary Glands
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
