Atypical sites of post-cholecystectomy bleeding. Vast subcapsular haematoma (*) seen on ultrasound (a), precontrast (b) and enhanced (c) CT 24 h after laparoscopic cholecystectomy, causing compression of the liver, treated by percutaneous drainage and transfusions. Note residual intraperitoneal air (+) d, e Paraduodenal and anterior pararenal haematoma (*) seen on unenhanced (d) CT on the 3rd postoperative day after laparoscopic cholecystectomy, with drainage (thick arrows) still in place, without contrast blushes, suggesting active bleeding on arterial-phase CT (e); size and attenuation of the hematoma tended to regress at follow-up CT (not shown) on conservative treatment, including transfusions
