PSEUDOCOARCTATION OF THE AORTA PRESENTING AS A MEDIASTINAL MASS WITH DYSPHAGIA

Pseudocoarctation is an uncommon anomaly thought to be caused by congenital elongation and kinking of the aorta. We report a case of pseudocoarctation of the aorta presenting as a superior mediastinal mass causing dysphagia. Aortography and echocardiography revealed dilatation of the aorta and an aneurysm below the level of the pseudocoarctation. The patient underwent operative repair of the pseudocoarctation and associated aneurysm with good symptomatic relief. Review of the literature and experience with this case demonstrate that pseudocoarctation of the aorta cannot necessarily be regarded as a benign condition. Surgical treatment is recommended for all symptomatic patients and for those with associated aneurysm formation.
