    Abstract:
    BACKGROUND: To demonstrate the radiologic-pathologic correlation of adenomyomatosis of gallbladder (GBA) and emphasize the role of high-resolution real-time ultrasound (RTUS) in the diagnosis of GBA. METHODS: Ten (four male and six female, mean age = 49 years) patients with proven GBA (three diffuse, three segmental, and four fundal) diagnosed by histopathology or confirmed by oral cholecystography (OCG) were reviewed. Radiologic studies included OCG (n = 8), RTUS (n = 8), and computed tomography (CT; n = 4). Six patients subsequently underwent cholecystectomy. RESULTS: Histopathologic correlation between pathologic specimens and OCG, RTUS, and CT was possible in six patients. The diagnostic criteria with ultrasound included numerous tiny intramural cysts containing echogenic foci with reverberation artifacts and associated segmental or diffuse gallbladder wall thickening. OCG with fatty meal demonstrated intramural diverticula. Localized fundal GBA was better visualized on RTUS and CT scan than on OCG. CONCLUSION: Accurate diagnosis of GBA may be made by either OCG or high-resolution RTUS preoperatively. CT scan may used as an alternative method to help make the diagnosis in equivocal cases.
