Fig. 2From: Rapidly progressive respiratory failure with multiple halo signs on computed tomography in a patient with primary cardiac angiosarcoma derived from the right atrium: a case reportChest radiograph and thoracic computed tomography (CT) on admission. a Chest radiograph on admission shows non-segmental bilateral lung infiltrations, predominantly in the right-sided middle to lower lung fields. b Non-enhanced thoracic CT shows non-segmental consolidation with ground-glass opacities or multiple scattered nodules in both the lung lobes. c Contrast-enhanced thoracic CT reveals a filling defect in the right atrium (black asterisks). d Enhanced electrocardiogram-gated cardiac CT reveals an inhomogeneously enhancing tumor in the right atrium (white asterisks)Back to article page
