This study aims to determine prevalence and sonographic features of gallbladder adenomyomatosis and polyps in a cohort.
Retrospective analysis of 2674 patients who underwent abdominal ultrasound.
Highly experienced sonographers performed exams with B-mode, color Doppler, and contrast-enhanced ultrasound.
Adenomyomatosis and polyps were classified based on morphology and vascularity.
Adenomyomatosis diagnosed in 32 patients (1.2%), characterized by thickened walls and RAS.
Gallbladder polyps identified in 123 patients (4.6%); mostly stable or minimal growth observed.
Only three patients required surgery, with two cholesterol polyps and one precancerous lesion.
