Gallbladder cholesterol polyp. a Ultrasonography (US) showed an isoechoic lesion, 1.4 × 0.6 cm in size. b On contrast-enhanced ultrasound (CEUS), the lesion showed synchronous enhancement with the gallbladder (GB) wall at 14 s in the arterial phase, and iso-enhancement in comparison to the normal GB wall. c As time passed, the contrast within the lesion showed simultaneous wash-out with the GB wall. d Postoperative pathological results: GB cholesterol polyps
