Pancreatic head adenocarcinoma. Malignant obstructive jaundice due to pancreatic head adenocarcinoma (pathologically proved) with moderate intra- and extra-hepatic biliary dilatation and PV thrombosis. Male patient, 55 years old, presented with jaundice, abdominal pain, anorexia, and cachexia. a Axial non-contrast, b axial oblique reformatted post-contrast (arterial phase), c axial (portal phase), and d axial (delayed phase) images showing fairly defined pancreatic head mass that is poorly enhancing at the arterial and venous phases, being isodense at delayed phases. e Coronal oblique MinIPreformatted MDCT cholangiography image showing moderately dilated CBD till its distal end where the mass encroaches upon it. f Coronal oblique MIP reformatted MDCT cholangiography images showing partially thrombosed PV
