GALL BLADDER - Cholelithiasis and hour-glass deformity

The gall bladder has been opened to show a constriction which markedly reduces the internal diameter of the organ. Alongside are some of the numerous small cholesterol stones found in the gall bladder.
This man presented at the age of 18 with symptoms suggestive of cholelithiasis; the gall bladder showed an hour-glass deformity and contained stones. Stones were also present in the common duct.
