(A) 53-year-old man with history of right pelvic chondrosarcoma presented with a new pelvic collections 1 month after excision and reconstructive surgery (arrow). CT guided aspiration revealed presence of a hematoma as shown on this non contrast enhanced axial CT image of the pelvis (A). A 12F biliary drainage catheter (used as a drainage catheter due to its multiple side holes) was placed followed by a single cycle of tPA. Follow-up CT on day 4 demonstrates near complete drainage of the hematoma as is shown in this axial CT image (B).
