Metastases to the bony pelvis is an unusual pattern of the spread of primar
y pancreatic tumors. The authors report the presence of metastatic disease
in the bony pelvis observed on bone scans in several patients who had been
treated recently for pancreatic carcinoma. When bone scans that show metast
atic disease in the pelvis are evaluated in patients with unknown primaries
, the diagnosis of pancreatic carcinoma should be considered.
