Magnetic resonance angiography of an ipsilateral double aortic arch due to persistent left fourth and fifth aortic arches.
Persistence of a fifth aortic arch with an ipsilateral fourth arch manifested as a double-lumen aortic arch (DLAA) is a rare congenital anomaly. We present one of the first cases diagnosed by magnetic resonance angiography (MRA) in a 7-year-old girl referred for treatment of subaortic membrane and aortic regurgitation.
