Abstract

Congenital anomalous aortic arches and subclavian arteries are relatively common, especially right aortic arch with an aberrent left subclavian artery which occurs in about 0.05 % of the populations. The radiologic findings of a plain chest X-ray are occasionally mistaken for a mediastinal tumor or an aortic aneurysm. This 48-year-old woman was admitted to the Severance Hospital because of known mediastinal widening in plain chest X- ray for 7 months. Chest CT scan and echocardiography confirmed the diagnosis of a right aortic arch with an aberrant left subclavian artery.
