Pseudocoarctation of the aorta complicated by thoracic aortic aneurysm.

Pseudocoarctation is a rare anomaly involving kinking or buckling of the aorta without a pressure gradient across the lesion, considered to be a benign entity warranting no specific intervention. An uncommon case of pseudocoarctation associated with aortic aneurysm formation in 21-year-old woman is described. Pathological findings suggested that the etiology was anomalous development of the aorta in association with pseudocoarctation; therefore, careful follow-up of patients affected by pseudocoarctation is mandatory.
