Mucinous Noncystic Colloid Carcinoma of the Pancreas with Solitary HepaticMetastasis: A Rare Presentation

Mucinous noncystic (colloid) carcinoma (MNCC) of the pancreas is considered an uncommon variant of ductal adenocarcinoma of the pancreas with specific histopathological and molecular features. We report the CT findings of large area of hypoattenuation and intratumoral calcification in a pathologically proven case of mucinous non-cystic carcinoma of the pancreas. MNCC of the pancreas is a distinct entity that needs to be radiologically differentiated from the ductal adenocarcinoma as usually it has more favorable outcome when compared to the rapidly fatal course of ductal adenocarcinomas. But in our index case, it was associated with a large solitary hepatic metastasis with similar calcific foci, which to the best of our knowledge has not been described in the English literature till date.c
