CTICasesCOVID-19 Associated Pulmonary Hemorrhage
Imaging findings
Initial chest CT shows findings of organizing pneumonia with symmetric peripheral ground-glass opacities. Subsequent chest radiographs over two days show rapid development of dense, symmetric consolidation in both upper lobes, with a sharp horizontal boundary. Non-contrast CT demonstrates exceedingly high attenuation consolidation in the upper lobes, and bronchoscopy confirmed alveolar hemorrhage.
Key takeaways
While diffuse alveolar hemorrhage typically presents with diffuse patchy or centrilobular nodules, it can rarely present with dense, lobar or symmetric upper lobe consolidation. This can occur in the setting of severe ARDS and coagulopathy associated with COVID-19.
