A 61-year-old female presented with persistent pain in the left breast following benign core needle biopsy. Diagnostic mammogram demonstrated a new small circumscribed mass in the upper outer quadrant of the left breast directly adjacent to the previously biopsied mass. Subsequent targeted Color Doppler ultrasound revealed a vascular mass with to and fro pulsatility. A diagnosis of breast pseudoaneurysm was made, a known albeit rare complication of breast core needle biopsy. The patient was treated with ultrasound guided thrombin injection into the pseudoaneurysm sac which resulted in complete sac thrombosis.
