case_images: 38-year-old man with right flank pain, nausea, and vomiting, diagnosed with acute pancreatitis due to right hydronephrosis. (a) Transverse section of the biliary tract and the right kidney on magnetic resonance cholangiopancreaticography (MRCP) showed grade 4 right hydronephrosis due to multiple renal stones (1) pushing the duodenum (2) and the head of pancreas (3) anteriorly. (b) Transverse section MRCP showed hydronephrosis obliterating the distal segment of the common bile duct (arrow) and dilatation of the proximal segment of common bile duct (4) and hepatic ducts (5). No dilatation of pancreatic duct (6) is seen.
