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.
超声检查是一种常用于诊断胆囊疾病的方法。在常规腹部超声检查（US）中，常可发现息肉样病变。这些病变的特征各异。由于大多数早期胆囊恶性肿瘤没有症状，因此区分良恶性至关重要。了解胆囊息肉样病变非常重要，以便在 US 检查发现胆囊内结节的患者中进行适当的鉴别诊断。本文总结了这些病变的诊断方法，并介绍了我们最近在超声造影方面的经验。文中还回顾了胆囊息肉样病变的临床和影像学特征。
