Metastasis of hepatocellular carcinoma to the colon demonstrated by Tc-99m PMT scintigraphy

Clin Nucl Med. 1993 Jun;18(6):512-5. doi: 10.1097/00003072-199306000-00012.


A 57-year-old man was found to have a tumor in the ascending colon after hepatic segmentectomy for ruptured hepatocellular carcinoma. Colonoscopy was performed, and metastasis of the hepatocellular carcinoma to the ascending colon was suspected based on the biopsy specimens obtained from the tumor. On hepatobiliary scintigraphy using Tc-99m PMT performed to confirm this diagnosis, Tc-99m PMT was clearly observed to accumulate in the tumor. Thus, the tumor was diagnosed as metastasis of hepatocellular carcinoma.
