Ultrasound demonstration of clip migration to Skin within 6 weeks of 11-gauge vacuum-assisted stereotactic breast biopsy.

A 39-year-old woman underwent 11-gauge vacuum-assisted stereotactic biopsy of a cluster of calcifications at the 5 o'clock location in the left breast. Initial clip placement was confirmed by mammograms to be at the biopsy site. The patient experienced episodic minimal bleeding at the skin entry site when she went home. The patient presented 6 weeks later with a history of progressive discomfort and lump at the stereotactic breast biopsy scar site. Ultrasound confirmed clip migration to the skin incision site. The clip was removed percutaneously by the radiologist, relieving the patient of her symptoms.
