During my regular health checkups I had observed following results for gall bladder during abdomen scan for last 3 years 2015: Normally distended wall is regular, evidence of calculi noted in the lumen measuring 3 mm. In the lumen no evidence of pericholecystic fluid noted. 2016: Normally distended wall is regular, No evidence of calculus/perfuid noted. Shows four polyp measuring around 2-3 mm 2017: partially distended with hperechoic foci along the wall s/o cholecterosis. So every year I am seeing somewhat different observations. Not sure what to make out from the scans.
