Figure 4
Chest CT-angiography of a 38-year-old patient with no pathological history with a positive PCR for COVID-19 pneumonia. Parenchymal window (A, C) shows peripheral foci of condensation. Mediastinal window (B, D) finds a bilateral proximal pulmonary embolism (endoluminal defects at the bilateral lobar level) as well as a left pleural effusion.
Figure 5
Thoracic CT angiography of a 42-year-old patient with positive PCR for COVID-19. Parenchymal window in the axial section (A) without injection shows peripheral bilateral ‘ground glass’ areas (arrow). The mediastinal window (B) in coronal reconstruction (MIP), reveals several bilateral endoluminal defects involving the lobar, segmental, and sub-segmental branches of the pulmonary artery (arrow).
