Diffuse abdominal uptake of technetium-99m-HDP after colectomy in Gardner's syndrome.

Abstract

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