Umbilical hernia simulating recurrent carcinoid on octreoscan.

Research output: Contribution to journalArticle


Physiologic bowel activity on In-111 octreotide imaging is commonly seen. However, on occasion, normal bowel activity may mimic lesions in the abdomen, which can be very difficult to differentiate, particularly after surgical intervention. We report a case of focal bowel activity simulating a lesion in a patient who had an In-111 octreotide scan (Octreoscan), postoperatively, looking for recurrent carcinoid. SPECT/CT demonstrated that the uptake was localized in the anterior abdomen, and corresponded to a loop of bowel within a ventral hernia at the site of surgical incision. The correlation with CT as well as the precise localization made possible by the fusion images helped avoid misinterpretation of this finding as possible recurrent carcinoid.
