(a) Chest radiograph and (b and c) axial computed tomography images in lung window settings depicting bronchiectasis in both lungs with superadded infection. Also note the origin of both the right and left main bronchi at the same level (arrows). Both bronchi were hyparterial in origin

Her chest radiograph showed bilateral basal bronchiectasis [Figure 1a]. The cardiac situs was normal, but an aberrant origin of the right subclavian artery from the aorta (distal to the left subclavian artery origin) was identified [Figure 1b, c and Figure 2]. CT also confirmed the presence of bilateral bronchiectasis [Figure 1b and c].
(a-c) Coronal and axial contrast-enhanced computed tomography images of the chest revealed an aberrant origin of the right subclavian artery from the aorta, distal to the left subclavian artery (arrows) and (d) sagittal reformatted image of the right lung reveals only a single major fissure dividing the lung into two lobes suggestive of left isomerism (arrows)

The cardiac situs was normal, but an aberrant origin of the right subclavian artery from the aorta (distal to the left subclavian artery origin) was identified [Figure 1b, c and Figure 2].
(a and b) Contrast-enhanced axial computed tomography image through the upper abdomen. There is evidence of polysplenia (+) with the stomach lying on the right side ( ) and the liver lying in the midline ( ). The inferior vena cava (curved arrow) is lying to the left of the aorta (arrow) which is midline in location. There is malrotation of bowel with whirling of the mesenteric vessels suggesting midgut volvulus (white arrow)

CT also showed malrotation of the small bowel with evidence of midgut volvulus [Figure 3].
