Rads of the thorax and abdomen – In the plain studies moderate dilation of the esophagus with gas is noted. Cranial to the heart a focal accumulation of mineral opaque foreign material is seen on one of the views. The trachea shows a moderate ventral and moderate right lateral deviation at the level of the thoracic aperture. The cranial aspect of the mediastinum is moderately widened and has approximately two times the width of the thoracic vertebral bodies at the same level. The esophagogram shows a markedly dilated esophagus starting in the cervical region and extending to the level of the base of the heart. On multiple views a dorsal pleuroperitoneal mesothelial remnant is seen.
The radiographic findings are in this radiographic study are suggestive for a congenital vascular ring anomaly. However some typical findings of a persistent 4th right aortic arch – such as focal leftward deviation of the trachea – are missing. Due to the level of the esophageal stenosis an aberrant right subclavian artery is not very likely.
Potential differentials such as congenital or acquired stricture cannot be ruled out entirely here.
CT angiography of the thorax and esophagoscopy are recommended here for further definition.
The findings of the lung are compatible with deteriorating aspiration pneumonia.
The dorsal pleuroperitoneal mesothelial remnant is an indirect radiographic sign of a congenital peritoneopericardial diaphragmatic hernia. Currently there is no evidence of organ displacement into the pericardium. Consider further ultrasonographic definition.
