Which of the following condition is associated with focal and diffuse thickening of gall bladder wall with high amplitude reflections and 'comet tail' aifacts on USG?
Focal diffuse thickening of gall bladder wall with high amplitude reflections and 'comet tail' aifacts on USG suggest the diagnosis of adenomyomatosis. Adenomyomatosis is a benign condition characterized by slow growth, enlarged gall bladder wall and hyperplasia of the gall bladder mucosa forming invaginations through the muscular layers, well known as 'Rokintansky-Aschoff sinuses' which causes the 'comet tail' tail aifact in the USG. It may produce focal, segmental or diffuse mural thickening.
