A 73-year-old female patient presented by obstructive jaundice. a–c Conventional images (axial and coronal T2WI) showed isointense signal intensity lesion involving the pancreatic head with encasement of the mesenteric vessels > 180° (yellow arrow). Dilated CBD down to its lower end (arrow in c). d–f) DWI and ADC maps revealed truly restricted pancreatic head mass with increased brightness with increasing of the b value denoting its malignant nature. The vascular encasement here appeared to be < 180° (resectable lesion). Multiple hepatic (d4) and bone (d3) deposits are detected rendering the lesion unresectable. The ADC value of the lesion ranged from 1.0 to 1.2 × 10−3 mm2/s
