Definition / general
  • Also called ectopia or choristoma
  • Normal tissue in abnormal location
  • Usually incidental
  • Includes liver parenchymal nodules, usually 2.5 cm or less, suspended to gallbladder by mesenteric stalk (DD: accessory lobe)
  • Gastric heterotopia arises as intramural nodules, plaques or polyps, in neck or cystic duct, rarely with peptic ulceration
  • Pancreatic heterotopia has acinar tissue, rarely islets, that may cause acute pancreatitis in gallbladder (Ryoikibetsu Shokogun Shirizu 1996;(9):360)
