COVID-19 Pneumonia

  • Etiology: COVID-19 virus
  • Imaging: ground glass opacities are bilateral / peripheral and subpleural / posterior / mid to lower lungs, evolution is halo sign seen early due to local inflammation + vascular congestion / then see progressive diffuse ground glass opacity as inflammation spreads to adjacent alveoli / finally see development of consolidative opacities as alveoli become filled with fluid + inflammatory cells, lymphadenopathy and pleural effusions are rare, crazy paving less common than in adults, CT more sensitive than CXR
