Urinary bladder diverticula are common and are frequently incidentally discovered. Many downstream complications can occur due to urinary stasis, such as bladder diverticular stones, infection, and malignancy. Understanding the physiology of bladder diverticula and potential pitfalls and mimics is critical to an accurate description of bladder diverticula and early detection of potential downstream complications. This pictorial review will first review the normal bladder histology and function, bladder diverticular types, and typical imaging features. The paper will then draw attention to technical pitfalls and potential mimics. Finally, we will review the downstream complications, including stones, infection, malignancy, and BCG-related changes.
膀胱憩室很常见，常常是在偶然情况下被发现。由于尿液潴留，可能会出现许多下游并发症，如膀胱憩室结石、感染和恶性肿瘤。了解膀胱憩室的生理学、潜在陷阱及类似病变对于准确描述膀胱憩室和早期发现潜在的下游并发症至关重要。本图像综述将首先回顾正常膀胱组织学和功能、膀胱憩室类型及典型影像学特征。本文还将关注技术陷阱和潜在的类似病变。最后，我们将回顾下游并发症，包括结石、感染、恶性肿瘤及卡介苗相关改变。
