Rokitansky-Aschoff sinuses

Dr Jeremy Jones et al.

Rokitansky-Aschoff sinuses are diverticula of the gallbladder wall which may be microscopic or macroscopic. Histologically, they are outpouchings of gallbladder mucosa that sit within the gallbladder muscle layer.

They are not of themselves considered abnormal, but may be associated with cholecystitis and adenomyomatosis.

  • Baron Carl von Rokitansky (1804-1878), pathologist in Vienna, Austria
