Gallbladder adenomyomatosis. a Ultrasonography (US) showed limited thickening at the bottom of the gallbladder (GB) wall, 1.3 × 1.0 cm in size. b On contrast-enhanced ultrasound (CEUS), the lesion showed heterogeneous iso-enhancement at 16 s in the arterial phase. c The contrast agent within the lesion then gradually showed wash-out with the GB wall. Honeycomb-like non-enhancement was observed during the entire CEUS procedure. d Postoperative pathological results: GB adenomyomatosis
