<p class="first" id="d13702702e101">Coronavirus Disease 2019 (COVID-19) is a pneumonia
caused by severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2). The outbreak began in Wuhan, China, and spread
rapidly, with many cases confirmed in multiple countries. Usually, after viral pneumonia
were clinical cured, the pulmonary lesions of majority patients will gradually be
absorbed to complete dissipation, very few severe patients may retain pulmonary interstitial
inflammation and fibrosis. In this case, we described one unique COVID-19 patient,
the symptoms were: dry cough, fatigue, poor appetite and subjective fever, moreover,
the patient was a non-smoker, had no pulmonary bullous, no history of tuberculosis,
and also no hypertension or diabetes. The patient received antiviral therapy, antibacterial
therapy, recombinant human interferon-α2a, vitamin C and oxygen inhalation. After
two weeks of treatment and observation, the patient was clinical cured and discharged.
However, two days later, the patient had a sudden chest stuffiness, CT images indicted:
his lung didn't heal like others, but developed a large pulmonary cavity in the lower
lobe of right lung. In hospital, the patient showed no symptoms of infection for another
14 days, and the pulmonary cavity remain unchanged. This case suggested: it is important
to follow convalescent COVID-19 patients, especially their lung CT images, to make
sure a fully recovery.
