There are at least 5 pancreatic lesions with contrast affinity in the arterial phase in the head, corpus and cauda. Largest is located in the pancreatic head adjacent to the common bile duct. These lesions are isoattenuated to the normal pancreatic parenchyma in the portovenous phase.
A stent is applied in the common bile duct and common hepatic duct. Small air pocket noted in the gallbladder.
Absent right kidney.
Multiple renal cysts of the left kidney, Bosniak I.
