摘要

梅克爾憩室是卵黃管發育異常最常見的一種，常發生在遠端迴腸的反腸繫膜側，在所有造成小兒腸套疊的病灶種類中，內翻性梅克爾憩室占的比例最高，並且需要緊急手術，然而，在臨床症狀對於鑑別診斷病灶導致腸套疊和原發性腸套疊仍有困難，所以影像學扮演很重要的角色，最常使用的影像檢查包括傳統消化道鋇劑攝影、超音波、核醫梅克爾憩室掃描、電腦斷層和血管攝影，這篇文章是討論電腦斷層在內翻性梅克爾憩室導致腸套疊的運用。

並列摘要

Meckel's diverticulum is the most common omphalomesenteric duct anomaly and occurs on the anti-mesenteric border of the distal ileum. An inverted Meckel's diverticulum is the most common pathologic leading point of intussusception in children and needs emergent operation. However, it is still a challenge to differentiate which children may have intussusceptions due to pathologic leading points from those who have idiopathic intussusceptions. Imaging plays an important role for diagnosis, because the varied and often nonspecific presentation and the wide spectrum of types of pathologic leading points. The frequent diagnostic modalities include conventional barium study, sonography, radionuclide Meckel scan, computed tomography and angiography. The aim of this report is to demonstrate the role of computed tomography (CT) in diagnosing intussuscepted Meckel diverticulum.
