Small cell carcinoma of the lung: primary site and hepatic metastases both detected on Tc-99m-pyrophosphate bone scan.

A case of small cell anaplastic carcinoma of the lung with hepatic secondaries has been found to accumulate Tc-99m-pyrophosphate in both lung primary and hepatic metastases and to our knowledge is the first such case reported in the literature. There was no radiographic evidence of calcification in the tumor or hepatic metastases.
