Female; 61 years old. Reason: eval pancreatitis / obstruction History: acute pancreatitis ABDOMEN:LIVER, BILIARY TRACT: Subcentimeter focus of arterial hyperenhancement in the right hepatic lobe near the dome without the washout or corresponding lesion on T2-weighted images, most likely due to transient perfusional differences (series 1502/537). No suspicious hepatic lesions. Status post cholecystectomy. Mild central intrahepatic bile duct dilation. New mild dilation of the common bile duct measuring up to 11 mm with no distal obstructing lesion evident, though stenosis at the level of the ampulla of Vater is a possibility.SPLEEN: No significant abnormality noted. Patent splenic vein. PANCREAS: Interval resolution of acute pancreatitis. New dilation of the main pancreatic duct in the dorsal pancreatic head measuring up to 8 mm with no distal obstructing lesion evident, though stenosis at the level of ampulla of Vater is a possibility. The degree of dilation is similar to ERCP images from 1/29/15, but new since prior MRI on 12/8/14. Note is made of normal caliber accessory pancreatic duct in the ventral pancreatic head and normal caliber main pancreatic duct in the body and tail of the pancreas. The accessory pancreatic duct is seen draining into a small superior accessory ampulla.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Stable atrophic native kidneys with scattered small cysts.Stable renal allograft in the right iliac fossa, again partially visualized. Stable large circumscribed cystic collection in the right lower quadrant abuts the renal allograft.RETROPERITONEUM, LYMPH NODES: Scattered subcentimeter retroperitoneal lymph nodes are not enlarged by size criteria.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Interval resolution of acute pancreatitis.2. New mild dilation of the common bile duct and main pancreatic duct in the dorsal pancreatic head without evidence of distal obstructing lesion, though stenosis at the level of the ampulla is a possibility. Of note, there is pancreatic ductal variant anatomy, further detailed above.
