Figure 1 Lung ultrasound findings in children with viral lower
respiratory tract infection (a, c) and in a woman with COVID-19
pneumonia (a, d), performed by the same pediatrician.
1a Lung ultrasound images of a 4 year old boy with viral
pneumonia - due to Coronavirus (non-COVID-19), Bocavirus and
Metapneumovirus coinfection- requiring respiratory assistance with
High-flow nasal oxygen at the pediatric department; ; lung ultrasound
shows areas of white lung with multiple, coalescent vertical artifacts
(B-lines, black arrowhead). A similar lung ultrasound pattern (multiple
vertical artifacts, B-lines, black arrowhead) was found in a 42 years
old woman with COVID-19 pneumonia and moderate respiratory distress
(1b ). 1c Lung ultrasound images of a 2 year old boy
with H1N1 Influenza pneumonia requiring respiratory assistance with
High-flow nasal oxygen at the pediatric department, showing subpleural
consolidations (hypoechoic areas, black arrow) and below areas of white
are evident. A similar lung ultrasound pattern (subpleural
consolidations - black arrow – with areas of white lung) was found in a
31 years old pregnant woman with COVID-19 pneumonia and acute
respiratory failure requiring admission in the intensive care unit
(1d ).
