INDIUM-111-LEUKOCYTE IMAGING - A CASE OF PERITONITIS MIMICKING INFLAMMATORY BOWEL-DISEASE

Leukocytes labeled with Tc-99m-HMPAO and (111)ln have been used extens ively in imaging inflammatory disorders, including inflammatory bowel disease (IBD), which has the appearance of tubular bowel activity. Per itonitis is inflammation of the serosal surfaces lining the peritoneal cavity which envelopes the bowel, giving a pattern of diffuse abdomin al uptake on imaging. We present a case of an elderly man with surgica lly and pathologically confirmed peritonitis whose preoperative leukoc yte scan mimicked the findings of IBD. Our findings suggest that diffu se peritonitis can mimic IBD on an (111)ln-leukocyte scan.
