“False-positive” double duct sign in a patient with MFCP (67 y, female). a Axial MDCT shows severely atrophic pancreas with stippled calcifications in long-standing CP. b In the head there is a hypovascular mass, which causes c abrupt cut-off (arows) of common bile duct and main pancreatic duct (double duct sign), highly suspicious for PDAC developing in CP. d ADC shows only minimally restricted diffusion of the mass (arrows) (ADC value 1.51 × 10− 3 mm2/s), which is more in favour of inflammation. Patient underwent surgery, which revealed an inflammatory mass and no cancer
