To present radiological aspects of jejunoileal diverticulosis and its complications.
Jejunoileal diverticulosis is a relatively rare and underestimated condition, which mostly affects the elderly. It is frequently asymptomatic but it can lead to significant complications requiring surgical treatment. Jejunoileal diverticulosis is far less common than colonic diverticulosis. Acquired small bowel diverticula are often numerous but the complication rate is low. Acute diverticulitis is the most frequent complication; its classic presentation involves the jejunum and is often non-severe. Diverticular hemorrhage is the second most common complication; CT scan examination is essential to determine the accurate topography of the pathological diverticula. Small bowel obstruction can occur through several mechanisms: adhesions, enterolith, and intussusception. Extra-intestinal gas without perforation and "pseudo-ischemic" appearance are non-pathological conditions that are important to diagnose in order to avoid surgery.
Jejunoileal diverticulosis usually does not show any symptoms but can lead to diagnostic challenges requiring evaluation by CT. CT scan signs of these complications and some pitfalls must be known.
介绍空回肠憩室病及其并发症的放射学表现。
空回肠憩室病是一种相对罕见且被低估的疾病，主要影响老年人。它通常无症状，但可导致需要手术治疗的严重并发症。空回肠憩室病远较结肠憩室病少见。获得性小肠憩室通常很多，但并发症发生率低。急性憩室炎是最常见的并发症；其典型表现累及空肠，且通常不严重。憩室出血是第二常见的并发症；CT 扫描检查对于确定病理性憩室的准确位置至关重要。小肠梗阻可通过几种机制发生：粘连、肠石和肠套叠。无穿孔的肠外积气和“假性缺血”外观是非病理性情况，对于诊断非常重要，以免导致手术。
空回肠憩室病通常无症状，但可能导致需要 CT 评估的诊断挑战。必须了解这些并发症的 CT 扫描征象和一些陷阱。
