An infarct (short for infarction) is a stroke caused by an interruption of a healthy blood supply to the brain. Old infarcts are not reversible. They are most commonly caused by the same risk factors that cause heart disease, including high blood pressure, poor cholesterol levels, diabetes, smoking and sometimes emboli (small particles such as blood clots or plaque that traveled from other parts of the body).

The pancreas is a long, flat gland that sits tucked behind the stomach in the upper abdomen. Its main function is to produce enzymes that help with digestion and hormones that help regulate the way the body processes sugar. Intraductal papillary mucinous neoplasm (IPMN) is a precancerous lesion of the pancreas with risk of developing into cancer over time.
The intrahepatic biliary duct is a tube that is inside the liver and transports bile in the liver. Dilatation is the expansion or widening of the duct. Dilatation of the bile duct can be due to several causes including obstruction (blockage) of the bile duct, presence of a cyst or mass in the bile duct, benign (non-cancerous) strictures or infection. Symptoms, if present, could include right upper quadrant pain and/or jaundice.
