Figure 2: Three-dimensional virtual reconstructed images
showing a) right sided aortic arch (asterik) with four-vessel
arch branching pattern having separate origins of left brachiocephalic
trunk (1 ), right common carotid artery (2 ), right
vertebral artery (3 ) and right subclavian artery (4 ). The
MAPCAs are seen arising from the DTA (arrows). b) Sagittal
image of the descending thoracic aorta showing the right-sided MAPCAs
(C1, C2, C3 ) arising from the DTA, with aneurysmal dilatations
along their course (arrows). c) Virtual bronchoscopy image at
the level of bronchus intermedius showing bilateral, smooth extrinsic
compression (arrows).
