Indium-111 octreotide uptake in the surgical scar

Indium-111 octreotide uptake has been reported in various somatostatin rece ptor positive tumors, granulomas and autoimmune diseases in which activated leucocytes may play a role, subcutaneous cavernous hemangioma and angiofib roma. We present Indium-111 octreotide uptake in a surgical abdominal scar tissue 1.5 and 6 months after surgery in a patient who had been treated for recurrent carcinoid tumor in the rectosigmoid junction. Indium-111 octreot ide uptake in a surgical scar may be related to the binding to somatostatin receptors in the activated lymphocytes and fibroblasts that is previously reported.
