Right aortic arch: CT. diagnosis.
Computer Tomography (CT) can be helpful in the detection and diagnosis of aortic arch malformations, particularly the retro-oesophageal right side aortic arch with aberrant left subclavian artery. Three adult Saudi patients with this anomaly where recently encountered and are herein presented. All the three patients had CT scans with clear demonstration of the right aortic arch. CT can confirm the presence of this aortic arch anomaly suspected from plain chest radiographs or can detect the vascular anomaly when the radiographs suggest the presence of a mediastinal mass. The condition of congenital anomalous right aortic arch is also briefly discussed.
