The halo sign as a chest computed tomography finding of COVID-19

摘要

A 36-year-old male patient from New Jersey, USA, with obesity, hypertension and diabetes, was admitted to our service presenting excessive sweating, tachypnea, tachycardia, fever (38.6°C), and blood oxygen level of 90%. The patient reported that 5 days before he had sought medical care in the United States for dry cough, nasal congestion, malaise and fever. Chest radiography ( ) and computed tomography (CT) ( ) at admission showed multiple small nodular opacities and diffuse consolidations in both lungs, with central and peripheral distribution as well as with ground-glass halo, which corresponds to the halo sign.
