Computed tomographic finding in adenomyomatosis of the gallbladder.
We report on an uncommon case of symptomatic generalized adenomyomatosis of the gallbladder. It was initially suspected by ultrasonography and further confirmed by computed tomography (CT). A postcontrast CT scan at the level of the gallbladder body demonstrated the characteristic rosary sign. The rosary sign is formed by the enhanced proliferative mucosal epithelium with the intramural diverticula surrounded by the unenhanced hypertrophied muscle coat of the gallbladder. Similar CT scans were obtained sequentially in the caudal direction. These CT scan findings indicated generalized adenomyomatosis of the gallbladder. The patient received a cholecystectomy. The pathologic report showed specific changes of adenomyomatosis corresponding to the findings on the CT scan. Generalized adenomyomatosis of the gallbladder, therefore, can be accurately diagnosed by CT.
