The so-called Rokitansky-Aschoff sinuses of the gall bladder are very rarely visualized roentgenographically. Less than a dozen proved cases have been reported in the literature. When radiographic visualization of these sinuses does occur, a definite diagnosis of chronic cholecystitis can be made and surgery is indicated. The pathologist frequently sees what are called Rokitansky-Aschoff sinuses, but it is rare for the surgeon to grossly identify these, and even rarer for the roentgenologist to visualize them.
The term Rokitansky-Aschoff sinuses, or Luschka's crypts of the gall bladder, is applied to deep outpouchings of mucosa extending into or through the muscular coat and into the perimuscular layers, leading to separation of the interstices and delicate walls of the muscle bundles. Normally the gall bladder muscle bundles are resistant to such outpouchings. In the presence of inflammation, however, these contractile structures become weakened with obstruction and chronic overdistention and the mucosa can readily
