Abstract
Contrast-enhanced chest computed tomography (CT) with dual-energy technique in a 69-year-old patient with coronavirus disease 2019 (COVID-19) pneumonia demonstrated ground-glass opacities, crazy paving, and patchy consolidation (Fig a). Furthermore, filling defects were seen in segmental arteries of both lower lobes in keeping with pulmonary embolism (Fig b, arrow). Bilateral deep vein thrombosis was present (Fig c, arrowheads). The iodine map illustrated multiple peripheral wedge-shaped perfusion defects not only in the lower but also in the upper lobes, suggesting more pronounced embolism than suspected from visible intraluminal filling defects (Fig d).
