There are numerous entities that can mimic acute appendicitis. Ultrasound and computed tomography are the most common first-line, cross-sectional imaging modalities in the acute care setting. Ideally, imaging will either confirm appendicitis or exclude it by identifying a normal appendix. In the latter scenario, an alternate diagnosis can frequently be established that range from genitourinary, gastrointestinal, to even abdominal wall processes. Imaging is especially helpful in cases of patients presenting with atypical signs/symptoms for acute appendicitis and those presenting with a classic presentation where an alternative diagnosis is determined. The correct diagnosis will allow the most appropriate clinical management and therapy; specifically, avoiding nonindicated surgery is essential. Common and uncommon mimics of acute appendicitis are discussed with specific attention to their sonographic and computed tomographic appearances.
有许多疾病可酷似急性阑尾炎。超声和计算机断层扫描是急性护理环境中最常用的一线横断面成像方式。理想情况下，成像检查要么证实为阑尾炎，要么通过发现正常阑尾将其排除。在后一种情况下，通常可以确立其他诊断，范围从泌尿生殖系统、胃肠道疾病，甚至到腹壁病变。成像检查对那些表现出急性阑尾炎非典型体征/症状的患者以及那些表现出典型症状但确诊为其他疾病的患者尤其有帮助。正确的诊断将有助于采取最恰当的临床管理和治疗措施；具体而言，避免不必要的手术至关重要。本文将讨论急性阑尾炎的常见和罕见的模仿疾病，并特别关注它们的超声和计算机断层扫描表现。
