Images of acute pneumonitis. A follow-up chest X-ray shows increasing extents of peribronchial consolidations and infiltrations in the left upper lung (A). A chest computed tomography reveals extensive parenchymal consolidations in the whole left lungs, air-fluid levels within the emphysematous bullae, and multiple reactive mediastinal lymph nodes; all of these findings indicated a suspicious of pneumonia (B, C, D).
