Contrast-enhanced abdominal ultrasonography. a Contrast-enhanced gallbladder fundal wall thickness with liver parenchyma in the early phase (yellow arrows). The image on the left is the reference image. b Direct liver invasion was suggested by the contrast-attenuated liver parenchyma on the gallbladder fossa in the delayed phase (red arrows). The image on the left is the reference image.
