MR-ANGIOGRAPHY OF CERVICAL AORTIC-ARCH

Cervical aortic arch, a rare congenital anomaly, is usually asymptomat ic. Its recognition by a non-invasive modality is desirable, In this c ase report, the diagnosis of a right cervical aortic arch in a 19-year -old man is made by magnetic resonance angiography. Cervical aortic ar ch 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 supraclavicula r fossa to symptoms simulating a respiratory tract infection. Hence it s diagnosis by non-invasive means is desirable. Reports of cervical ao rtic arch diagnosed by computed tomography and magnetic resonance imag ing (MRI) have appeared in the recent literature [2-4]. We report a ca se of cervical aortic arch diagnosed by magnetic resonance angiography (MRA).
