Appendiceal intussusception is rare with an estimated incidence of 0.01%. Although it is infrequently encountered, the few documented cases of this entity have shown it may mimic or indicate an underlying neoplasm when evaluated with colonoscopy. With the abundant use of multi-detector CT and increased utility of CT colonography, awareness of the radiologic findings of this condition has become increasingly important. Appendiceal intussusception, while potentially pathologic in its own right, may mimic or even coexist with other pathologies, both malignant and benign. We present a case of adult appendiceal intussusception without a "lead point" that was successfully diagnosed by CT imaging.
阑尾肠套叠较为罕见，估计发病率为 0.01%。尽管它很少见，但已记录的少数此类病例表明，在进行结肠镜检查时，它可能会模拟或提示潜在的肿瘤。随着多探测器 CT 的广泛应用和 CT 结肠成像的增加，对这种疾病的放射学表现的认识变得越来越重要。阑尾肠套叠本身可能具有潜在的病理性，但可能会模拟甚至共存其他病理学，包括恶性和良性病变。我们提出了一个没有“先导点”的成人阑尾肠套叠的病例，该病例通过 CT 成像成功诊断。
