Abdominal patterns of indium-111 labeled leukocyte imaging.
In-111 oxine WBC abdominal scanning is now a widely accepted technique for the detection of abdominal infectious processes. High sensitivity and specificity are achieved. In-111 labeled leukocyte accumulation, however, does not always suggest the diagnosis of abscess. Higher specificity could be obtained by the knowledge of the In-111 leukocyte distribution pattern in the abdomen in other pathologic states like inflammation of abdominal wounds, stoma; surgical complication without abscess formation; inflammatory or ischemic bowel disease; or swallowing leukocytes which subsequently are visualized in the intestinal lumen. One hundred fifty-two consecutive WBC scans performed over 18 months were reviewed and classified according to their pattern of uptake: 96 cases showed no abdominal uptake, and 56 had accumulation of leukocytes in the abdomen. Twenty-eight of these patients had proven abdominal abscess, and the remaining 26 were positive due to other causes. This report briefly discusses the distribution pattern of In-111 labeled leukocytes in the latter patients and compares the results obtained using different diagnostic criteria.
