This is a young man with pneumonia. Also note the presence of bronchial breath sounds.
Patient 4
This is a young man with bilateral extensive pneumonia from SARS-CoV-2 infection (COVID-19).
Patient 5
This is an older woman who developed pulmonary toxicity from a biologic agent used to treat underlying lung cancer.
