| Abstract: | Ultrasound is a frequently used diagnostic tool for gallbladder diseases. Polypoid lesions are commonly depicted at routine abdominal ultrasonography (US). The characteristics of these lesions vary. Since most early malignant tumors in the gallbladder are asymptomatic, differentiation between malignancy and benignity is crucial. Knowledge of gallbladder polypoid lesions is important so that they can be appropriately included in the differential diagnosis in patients presenting with intra-gallbladder nodules on US. This article summarizes the algorithmic approach to the diagnosis of these lesions and our recent experience with contrast-enhanced US. The clinical and imaging features of gallbladder polypoid lesions are reviewed. |
