The case of an otherwise healthy 77-year-old man complaining of fever and cough for 7 days (mild phenotype). LUS and CXR were in disagreement. LUS showed a high probability pattern for COVID-19 pneumonia. The LUS scans reported in the bottom show the patchy and bilateral distribution of clusters of B-lines and light beam (1, 2, 4) with some irregularity of the pleural line (1, 4), alternating with normal A-lines pattern (3). CXR in the upper right panel was read negative. Corresponding CT scan in the upper left panel shows bilateral GGO and was considered typical appearance. The points numbered in the CT image correspond to the 4 LUS scans. Viral RT-PCR was positive.
