Pancreatic mass with the following characteristics:
Located in the tail, 3 cm from the tip (the tail is long, extending inferior to the spleen), it measures 18 x 25 x 16 cm. Hypodense with 6 mm nodule calcification at the centre, margins discrete but not smooth. It shows avid solid contrast enhancement only in the arterial phase, with contrast washout in the venous phase (enhancement does not parallel blood vessels, so the lesion is not an aneurysm). There was no dilatation of the pancreatic duct distal to the lesion, no atrophy of the tail parenchyma distal to the lesion, and no local peripancreatic infiltration.
Ampulla characteristics:
Measuring 8 x 8 x 8 mm and protruding into the duodenal lumen. No arterial enhancement with moderate venous enhancement similar to duodenal wall; enhancement does not appear mass-like. Pancreaticoduodenal groove fat is normal.
Liver characteristics:
Solitary 16 x 17 x 14 mm nodule in the superior subcapsular aspect of segment II; the nodule is hyper-vascular in arterial phase and washed out and becomes imperceptible in porto-venous phase. The enhancement pattern parallels that of the pancreatic tail mass. Four incidental simple hepatic cysts are present, measuring 7, 11, 12, and 32 mm.
