Although endoscopic ultrasonography (EUS) is commonly used to examine lesions in the gallbladder, its ability to accurately diagnose adenomyomatosis (ADM) has not been evaluated. We compared the accuracy of EUS and various other imaging techniques in the diagnosis of ADM. Thirty‐one patients undergoing cholecystectomy after elevated lesions were found in the gallbladder by various imaging techniques were studied retrospectively. Based on histopathologic examination, the sensitivity and specificity of EUS were evaluated in ADM. The sensitivity of abdominal ultrasonography, CT and ERCP in ADM were also evaluated. Of the 11 patients diagnosed with ADM by EUS, 9 cases were confirmed histologically (81.8%). Of the 11 patients with histologic diagnosis of ADM, 9 were accurately diagnosed preoperatively by EUS (81.8%). EUS proved more reliable for diagnosis of ADM than the other imaging techniques. Important diagnostic features include preservation of the three‐layered structure of the gallbladder, wall‐thickening exceeding 3 mm, and 2 or more Rokitansky‐Aschoff sinuses occurring within a 1 cm area of the gallbladder.
