Axial contrast-enhanced CT images. The image on the left shows a large VSD with a diameter of 1.8 cm (arrow head) and an ASD (arrow). MAPCA from the descending aorta (right). Note the absent pulmonary trunk, right ventricular hypertrophy and multiple, peripherally located, wedge-shaped lung lesions representing pulmonary emboli.

Furthermore, major aortopulmonary collateral arteries (MAPCA) arising from the descending aorta, an obliterated ductus arteriosus, and a dilatation of the aortic root (diameter 5.0 cm) were observed (Fig. 1).
Axial contrast-enhanced CT images showing left upper lobe pulmonary artery with filling defects representing wall adherent thrombi (arrow head) and reactive hilar lymphadenopathy (arrow, upper left), multiple peripherally located pulmonary lesions (upper right). 3D volume-rendered image demonstrating several MAPCA from the descending aorta (lower left). Wedge-shaped peripheral splenic defects representing splenic emboli (lower right).

The patient demonstrated multiple pulmonary and splenic emboli (Fig. 2).  
Non-enhanced cranial CT images showing hypoattenuating lesions in the left cerebral peduncle, in the right occipital lobe, thalamus, and cuneus (arrows), consistent with embolic infarctions.

Several hypoattenuating cerebral and cerebellar lesions were predominantly localized in the right hemisphere consistent with thromboembolic events (Fig. 3).
