Courvoisier's law
Introduction
Courvoisier’s law (or Courvoisier syndrome, or Courvoisier’s sign) states that in the presence of a palpable gall bladder, jaundice is unlikely to be caused by gallstones. This is because gallstones are formed over a longer period of time, and this results in a shrunken, fibrotic gall bladder which does not distend easily. Therefore the gall bladder is more often enlarged in pathologies that cause obstruction of the biliary tree over a shorter period of time such as pancreatic malignancy.[1]
It is named for Ludwig Georg Courvoisier.[2]

-
Cholangiocarcinoma has caused patient’s gall bladder to become markedly dilated, and therefore, easily palpable (A). Note skin is also jaundiced due to biliary tract obstruction. -
CT sagital image demonstrates dilated gall bladder (B), dilated common bile duct (C), and dilated intrahepatic ducts (D). Courvoisier described the same findings in patients with pancreatic cancer.
