VIEWER DISCRETION ADVISED--Partial Nudity and Offensive Language: This video demonstrates ultrasound guided aspiration of a large breast abscess. About 15 mL total of purulent material were removed. After 24 hours of intravenous clindamycin the patient failed "outpatient" treatment in the observation unit. On repeat ultrasound the abscess had returned and the patient required admission to the hospital for surgical incision and drainage in the operating room. We thank our patient for graciously allowing this video to be filmed.
