Findings

There is focal severe dilation of the esophagus cranial to the heart on the right lateral projection. There is focal leftward deviation of the trachea just cranial to the heart best noted on the VD projection. The heart is enlarged. The pulmonary parenchyma is within normal limits. The liver is enlarged compatible with the patients age. There are only 7 sternal segments.

Differential Diagnosis

Segmental severe megaesophagus cranial to the heart base with leftward deviation of the trachea. These radiographic changes are compatible with a persistent right aortic arch. Cardiomegaly may indicate other congenital heart disease.

Diagnosis

PRAA was surgically ligated. There was no indication of additional heart disease, although echocardiography was not performed.
