    As emergency physicians perform bedside ultrasound with greater frequency, greater numbers of incidental and potentially unfamiliar sonographic findings will be encountered.
    Illustrate, discuss, and briefly review literature regarding one such finding and diagnosis in right upper quadrant sonography.
    A middle-aged woman was evaluated in the Emergency Department for abdominal pain. Limited bedside sonography of the gallbladder revealed mural thickening and comet-tailing. A diagnosis of adenomyomatosis was made.
    Gallbladder adenomyomatosis can produce ultrasound findings similar to those of more serious and emergent gallbladder diseases. Cognizance of the sonographic details and typical clinical characteristics will allow the emergency physician to appropriately assess and disposition patients with this condition.
