We report the case of a 56-year-old woman with a presyncopal episode followed by melena. A sentinel clot sign in the pancreatic duct on precontrast computed tomography and the presence of a splenic artery aneurysm on postcontrast computed tomography strongly suggested a fistula between the aneurysm and the duct, as visualized by magnetic resonance imaging. The patient was treated successfully by complete embolization of the splenic artery aneurysm.

The hypertrophic uncinate process of the pancreas wrapping the superior mesenteric vein and artery was discovered during surgery on a patient with nodular chronic pancreatitis. Such a rare anomaly has never been noted in the English literature so far as we have been able to find. This malformation of the pancreatic uncinate process was considered to be due to excess fusion between the ventral and dorsal pancreatic anlages during embryonic stage.

A 71-year-old man presented to our hospital with obstructive jaundice, found to be caused by a huge liver cyst which was centrally located and riding on the hilum. Percutaneous transhepatic cyst drainage was performed, following which obstruction of the bile duct was relieved and the jaundice subsided. As jaundice recurred after removal of the drainage tube, the patient underwent deroofing, since when he has remained well. Only 13 cases of liver cysts producing obstructive jaundice have been reported in the English literature, most of which were characteristically enormous, located centrally, and riding on the hilum. Liver cysts possessing such features are likely to cause obstructive jaundice by compressing the hepatic hilum. Cyst drainage is helpful for ameliorating the jaundice and making an accurate diagnosis; however, subsequent deroofing or injection therapy is necessary to prevent recurrence.
