COVID-19 complicated by strange pulmonary fibrosis (preprint)

BackgroundThe lung CT of COVID-19 has characteristic changes, showing scattered ground-glass changes extrapulmonary zone. However, we observe a case of early infection of COVID-19 in a patient who did not show classic CT changes, but shows characteristic pulmonary fibrosis.Case presentationWe reported a patient who was infected in the early stage of the COVID epidemic without any treatment. The extrapulmonary zone showed symmetrical and diffuse fibrotic changes.Conclusionsthe lungs of COVID-19 may not show scattered ground-glass changes, but show symmetrical, diffuse pulmonary fibrosis in extrapulmonary, suggests that there may be other mechanisms other than infection involved in the changes in the lungs.
