Case 3 imaging findings: (A) Anterior-posterior chest radiograph at the time of presentation to the emergency department demonstrating diffuse peripherally-based bilateral patchy opacities. Lung point-of-care ultrasound in the emergency department was remarkable for confluent B-lines posterior (B, arrows), as well as an irregular pleural line with subpleural consolidations (asterisk). A lateral view (C) in the mid-anterior axillary line showed similar B-lines (arrow) and an irregular pleural line (asterisk).
