There is a wide spectrum of nonneoplastic causes of biliary stricture that can pose a significant challenge to clinicians and radiologists. Imaging plays a key role in differentiating benign from malignant strictures, defining the extent, and directing the biopsy. We describe the salient clinical and imaging manifestations of benign biliary strictures that will help radiologists to accurately diagnose these entities.
Accurate diagnosis and management are based on correlating imaging findings with epidemiologic, clinical, and laboratory data. Cross-sectional imaging modalities permit precise localization of the site and length of the segment involved, thereby serving as a road map to surgery, and permit exclusion of underlying malignancy.
胆管狭窄的非肿瘤性病因范围广泛,这给临床医生和放射科医生带来了巨大的挑战。影像学在区分良恶性狭窄、确定狭窄范围和指导活检方面起着关键作用。我们描述了良性胆管狭窄的显著临床和影像学表现,这将有助于放射科医生准确诊断这些疾病。
准确的诊断和治疗基于将影像学发现与流行病学、临床和实验室数据相关联。影像学检查方法可以精确地定位受累部位和长度,从而为手术提供路线图,并排除潜在的恶性肿瘤。
