Illustration of a vacuum assisted evacuation of hematoma in patient number 9. Vacuum assisted excision of a discordant lesion (A) at core biopsy resulted in a palpable painful hematoma. Ultrasound image of the 5.5x4.0 cm hematoma (B). Complete evacuation of the hematoma with sparing of hematoma wall (C); Large arrows indicate needle’s shaft and small white arrows indicate hematoma wall
