Tuberculosis of the small bowel with perforation and hematogenous spread in a renal transplant recipient

A 41-year-old male was admitted because of acute abdomen. A flat plate of the abdomen suggested pneumoperitoneum and a chest X-ray an infiltrate in the right upper lobe. The patient was a renal allograft recipient and was on immunosuppressive therapy with azathioprine, cyclosporine and steroids. At laparatomy inflammatory thickening of the bowel wall was found in the terminal ileum with necrotic areas and two sites of perforation. The involved terminal ileum was removed together with a right hemicolectomy. The resected segment showed exudative ileal tuberculosis and fibrinous and purulent peritonitis. During the postoperative period rapid hematogenous spread of tuberculosis developed with progressive reduction of respiratory function followed by ARDS. Autopsy revealed tuberculosis in all organs including the transplanted kidney.
