Porro describes a case of congenital obliteration of the esophagus which ended in a cecal pouch about one inch below the inferior portion of the glottidean aperture and from this point to the stomach only measured an inch; there was also tracheal communication.

The child was noticed to take to the breast with avidity, but after a little suckling it would cough, become livid, and reject most of the milk through the nose, in this way almost suffocating at each paroxysm; it died on the third day.
In some cases the esophagus is divided, one portion opening into the bronchial or other thoracic organs.

Brentano describes an infant dying ten days after birth whose esophagus was divided into two portions, one terminating in a culdesac, the other opening into the bronchi; the left kidney was also displaced downward.

Blasius describes an anomalous case of duplication of the esophagus.

Grashuys, and subsequently Vicq d'Azir, saw a dilatation of the esophagus resembling the crop of a bird.
Anomalies of the Lungs .-- Carper describes a fetus of thirty-seven weeks in whose thorax he found a very voluminous thymus gland but no lungs.
These organs were simply represented by two little oval bodies having no lobes, with the color of the tissue of the liver.
