Three cases are presented in which a fold occurred along the posterior wall of the gallbladder at the junction of the body and infundibulum at cholecystosonography. On the initial supine scans, this finding suggested a small polyp in 1 case and a calculus in the other 2. Familiarity with this normal variant as well as adherence to correct scan methodology should help to further reduce erroneous diagnoses.
