MR angiography of cervical aortic arch

Cervical aortic arch, a rare congenital anomaly, is usually asymptomatic. Its recognition by a non-invasive modality is desirable, In this case report, the diagnosis of a right cervical aortic arch in a 19-year-old man is made by magnetic resonance angiography. Cervical aortic arch is a rare congenital anomaly with only 50 cases reported by 1989 [1]. Though it may be associated with cardiac or aortic anomalies, this condition commonly occurs as an isolated anomaly and is usually silent. Presenting features vary from a pulsatile mass in the supraclavicular fossa to symptoms simulating a respiratory tract infection. Hence its diagnosis by non-invasive means is desirable. Reports of cervical aortic arch diagnosed by computed tomography and magnetic resonance imaging (MRI) have appeared in the recent literature [2-4]. We report a case of cervical aortic arch diagnosed by magnetic resonance angiography (MRA).
