Abstract
We present an atypical case of a 69-year-old woman with recurrent episodes of acute pancreatitis and a background history of mucinous colorectal adenocarcinoma. It is emphasized that in the framework of biliary malignant obstruction, modern non-invasive techniques like Magnetic Resonance Imaging (MRI) with hepatospecific contrast agent and Positron Emission Tomography (PET) may help establish the specific cause of the obstruction before any biliary decompression procedure is carried out. This strategy has the potential to prevent from more important tumour spread and provide a greater chance for curative surgery when applicable.
