Figure 1. Transabdominal ultrasound shows an elevated lesion (white arrowheads), 25 mm x 20 mm x 11 mm in size, on the liver bed side of the gall bladder neck. Its shallow part is unevenly hyperechoic but its deep part is irregularly hypoechoic with an outermost hyperechoic layer thickened beneaththe lesion. At the peritoneal side of the neck there is another small elevated lesion (black arrows), 3–4 mm in height, with a normal outermost hyperechoic layer. The gall bladder contains a small amount of biliary sludge (black arrowheads) moving freely with changes in position.
