Iatrogenic breast pseudoaneurysm in a lactating female: A rare breast emergency treated with ultrasound guided thrombin administration.

Pseudoaneurysm development is a well-recognized consequence of arterial injury, frequently observed in procedures involving arterial groin access. Breast emergencies are infrequent but need prompt attention. We present a notable case of breast pseudoaneurysm postcore needle biopsy, incidentally, identified through subsequent magnetic resonance imaging.
