A 54-year-old female patient presented with recurrent cough and sputum production over the past year and was hospitalized several times. CT examination revealed exudative lesions in both lungs, which were partially absorbed after treatment. However, they recurred shortly after discharge, and the patient had to be readmitted. In the past year, the patient had been hospitalized six times, and her throat swabs were positive for SARS-CoV-2 at four different points in time. After receiving anti-infective and antiviral treatment in other hospitals, the above symptoms were relieved. The patient tested negative for SARS-CoV-2, but symptoms recurred soon after. Eventually, the diagnosis of Goods syndrome was made based on the presence of B-cell loss, decreased immunoglobulin levels, an inverted CD4+/CD8+ ratio on admission, and a previous history of thymoma.
