Rectal carcinoid metastatic to the skeleton. Scintigraphic and radiographic correlation.

Compared to other primary neoplasms, bone metastases from carcinoid tumor are rare. Because some lesions may be clinically or radiographically occult, the radionuclide bone scan can be very helpful in delineating the extent of disease. The authors report a case of a patient with clinically occult widespread metastatic disease detected by bone scan, with radiographic correlation.
