Intense uptake of In-111 satumomab pendetide in an inflammatory mass

Intensely increased upper abdominal uptake of In-111 labeled anti-tumor associated glycoprotein in a patient with a history of pancreatic carcinoma persisted over 6 days in the same location. At laparotomy chronic inflammation, fibrosis, calcification, and lymph node granulomas were found, but no tumor. The patient remained tumor free 8 months later.
