Soft-tissue case 32. Presentation

Elijah Dixon; Barry Steed; Francis Sutherland; Phillip Mitchell

A 29-year-old man was using a circular saw when a large piece of plywood was “kicked back” from the saw and struck him in the right lower quadrant of the abdomen. When seen in the Emergency Department he was hemodynamically stable. He had some tenderness over the right anterior superior iliac spine with some superficial abrasions in that area. He was admitted overnight for observation. Because of persistent tenderness in the right lower quadrant an enhanced computed tomography scan of the abdomen and pelvis was obtained. Infusion CT scans of the abdomen are shown at presentation (Fig. 1) and 4 weeks later (Fig. 2).
