Enterogenous cysts have been found in close relation to almost every portion of the intestinal tract. They have occurred also outside the abdomen, chiefly in the mediastinum.1 These cysts usually duplicate the layers and the mucosa of the intestine from which they are derived and may in this manner be differentiated histologically from other cysts, such as those of dermoid or lymphatic type. The appearance of the epithelial lining of the cystic cavities may vary considerably, since distention and inflammatory reactions may cause changes. Glands resembling those present in the intestine are often noted in the submucosal layer.
The largest number of cysts of enterogenous origin have been found in the region of the obliterated omphalomesenteric duct. For this reason, many authors have stated the belief that these cysts are derived from remnants of this structure. They are considered closely related, then, to Meckel's diverticulum. The latter may be
