Evaluation of causal heart diseases in cardioembolic stroke by cardiac computed tomography

Figure 21  Pulmonary arteriovenous malformation. A 31-year-old woman hospitalized with acute ischemic stroke underwent chest computed tomography (CT) to further evaluate a nodular shadow in right lower lung field on chest radiography. A: Diffusion-weighted brain magnetic resonance imaging shows hyperintense lesions in left insula and left parietal lobe (arrowheads); B: Non-contrast chest CT shows nodular shadow in lateral basal segment of right inferior lobe (arrow); C–E: Maximum intensity projection reconstruction images (C: Axial; D: Coronal) and three-dimensional volume-rendered image (E) of contrast-enhanced CT show pulmonary arteriovenous malformation in lateral basal segment of right inferior lobe (arrow).
