47 year old male with history of hypertension admitted for COVID-19 pneumonia complicated by acute respiratory distress syndrome requiring intubation/tracheostomy. On the day of presentation and PCR testing, AP portable radiograph (A) shows ill-defined left lower lobe opacities. The patient was intubated on HD 2 and repeat AP radiograph (B) on HD 7 shows worsening now bilateral airspace opacities. On HD 26, AP portable radiograph (C) showed improved airspace opacities, but a new pneumotocele containing an air-fluid level in the left lung (arrow) and small pleural effusions (arrowheads). Axial (D) images from a same day contrast-enhanced CT chest show multi-septated spaces containing air and fluid, felt to represent a combination of pneumatoceles and loculated hydropneumothorax (arrowheads).
