DIFFUSE ABDOMINAL UPTAKE OF TECHNETIUM-99M-HDP AFTER COLECTOMY IN GARDNERS-SYNDROME

A 37-yr-old man presented with increasing abdominal girth and multiple palpable intra-abdominal masses 3 yr after colectomy for polyposis co li. Whole-body skeletal scintigraphy performed prior to laparotomy dem onstrated diffuse abdominal uptake of Tc-99m-HDP consistent with mesen teric fibromatosis confirmed at surgery. When diffuse abdominal uptake of skeletal imaging agents occurs in patients with prior colectomy fo r polyposis coli, mesenteric fibromatosis as a manifestation of Gardne r's syndrome should be suspected. This case illustrates another cause of diffuse abdominal uptake of skeletal imaging agents.
