Magnetic resonance imaging findings of undifferentiated carcinoma with osteoclast-like giant cells of pancreas

Abstract

Undifferentiated carcinoma with osteoclast-like giant cells is a rare pancreatic and periampullary neoplasm with less than 50 cases reported in the literature. Pathologically, this tumor mimics a giant cell tumor in bones. We report a case of undifferentiated carcinoma with osteoclast-like giant cells in a 55-year-old man presenting as a pancreatic mass with associated regional and distant lymphadenopathy. On T1- and T2-weighted images, the mass shows dark signal intensity which was atypical for a pancreatic adenocarcinoma.
