Pulmonary - Light Beam Sign (COVID-19)
Caption
Seen here is a "Light Beam Sign" in a patient with COVID-19 pneumonia. The on-and-off effect of the hyperecchyoic vertical artifact is believed to occur as a result of ground glass alterations in lung parenchyma. At times the light beams or B-lines cover A-lines; and at other times the A-lines remain visible in the background. Renato Melo, Emergency Physician at Hospital das Clínicas de Marília-SP, Brazil.
