Figure 1 Development, treatment, and treatment complication of a retroperitoneal (psoas) abscess in a patient with Crohn's disease who did not respond to medical therapy. (A) Retroperitoneal phlegmon (arrow), presumably the result of transmural bowel inflammation with fistulization and direct penetration of bacteria from the diseased bowel. (B) Two weeks later, an abscess cavity is apparent (arrow), presumably the result of fibrin deposition encasing the bacteria and inflammatory cells. (C) A retroperitoneal percutaneous drain has been inserted into the abscess cavity. (D) Bacterial contamination of the subcutaneous tissues after surgical resection and drain removal resulted in a non-necrotizing, gas-forming soft tissue infection (double arrow).
