Figure 2. MRCP showed a major obstruction of the distal common bile duct (A) caused by an inhomogeneous pancreatic head mass, resulting in significant intrahepatic and extrahepatic biliary dilatation. The gallbladder is markedly distended, consistent with biliary stasis. Axial T2-weighted MRI scan (B) showing severe atrophy of the pancreatic body and tail, with an absence of the dorsal pancreatic parenchyma, confirming the diagnosis of ADP. The red arrow indicates a large, inhomogeneous mass in the pancreatic head, compressing the common bile duct and leading to biliary obstruction.
