MDP uptake in peritoneal carcinomatosis and Krukenberg tumors from mucinous adenocarcinoma

Abstract

Altered biodistribution of Tc-99m methylene diphosphonate is a common occurrence on bone scintigraphy and mucin-producing neoplasms of the gastrointestinal tract are associated with dystrophic uptake. In addition to the uptake in the primary tumor, activity has been reported in metastasis within lymph nodes and liver. We present a case of Tc-99m methylene diphosphonate uptake in peritoneal carcinomatosis and metastatic Krukenberg tumors from a primary mucinous adenocarcinoma of the descending colon. Each of these findings is uncommon and their combination in this case is particularly unique.
