The intraluminal diverticulum of the duodenum is very rare; it is an anatomical sac like formation, located in the interior of the duodenum and communicating with it through an orifice situated a the upper pole of the diverticulum where the wall is covered by mucosa on both faces. It has interesting etiopathogenic problems. We present an observation after reviewing the corresponding literature. It was a 32-year old woman suffering from moderate epigastric pains, pyrosis, chronic constipation, markedly nervous. The epigastric pain was unrelated to food or physical efforts. The physical examination showed slight epigastric pain. The gastroduodenal radiological examination showed in the second part of the duodenum a particular image, pear-shaped, homogeneous, impregnated in barium; this image was surrounded by a radiotransparent halo which changed with the patient's position. It has been seen that the diverticulum changes in size and position in agreement with the peristaltism, without ever obstructing the passage through the duodenum. A review is made of the literature and history of intraluminal diverticulum.
十二指肠腔内憩室非常罕见；它是一种解剖学上的囊状结构，位于十二指肠内部，并通过憩室上极的一个孔与十二指肠相通，该孔处憩室壁两面均被黏膜覆盖。它存在一些有趣的病因问题。我们在查阅相关文献后呈现一例观察病例。患者为一名32岁女性，患有中度上腹部疼痛、胃灼热、慢性便秘，且明显焦虑。上腹部疼痛与饮食或体力活动无关。体格检查显示有轻微上腹部疼痛。胃十二指肠放射学检查显示在十二指肠第二部有一特殊影像，呈梨形，均匀一致，钡剂充盈；该影像被一个透光晕环绕，且随患者体位改变。已观察到憩室大小和位置会随蠕动而变化，但从未阻塞十二指肠通道。本文对腔内憩室的文献和病史进行了综述。
