Abstract
US, Cholangiography and CT were applied for the diagnosis of adenomyomatosis of the gallbladder (GB) in fourteen patients (G type 3, S type 8, F type 3).
1) G type: (US) Diffuse thickening of the GB wall and micro cystic areas can be demonstrated except mild dilatation of RAS. (Cholangiogram) The characteristic pearl beaded appearence (RA-sign) can be seen around the entire GB, especially in ERC or postcontraction on DIG. (CT) Diffuse thick-walled GB is seen, and sometimes also many micro cystic low density areas within the wall.
2) S type: (US) Compartmentalization of the GB (hour-glass deformity), segmental wall thickening, micro cystic areas are seen and sometimes comet like echo or triangle sign. (Cholangiogram)Cholangiogram shows stricture and distally narrowed lumen of the GB, but RA-sign appears only a few cases. (CT) Markedly contrast enhanced mass is seen in the GB.
3) F type: (US) Fundal thickening of the GB and micro cystic areas can be showed except very small lesion. (Cholangiogram) A filling defect of the fundus with small niche or RA-sign is visible.
