Chest Radiograph and CT Findings in Patients Hospitalized with Breakthrough COVID-19.

Abstract

Charts of 60 hospitalized patients that tested positive for SARS-CoV-2 were reviewed for a prior history of COVID-19 vaccination. Eight (13.3%) such patients were identified and included for analysis (mean age, 54 years; range 34-81 years; four women). Patients received either two doses of Pfizer-BioNTech (n = 6), two doses of Moderna (n = 1), or one dose of Johnson and Johnson (n = 1). Five (63%) patients were immunosuppressed at the time of presentation, and six (75%) reported respiratory symptoms. Most of the patients had normal radiographs (4 of 7; 57%). The most common chest CT findings were ground glass opacities (three of five), with mild to moderate severity scores (average, 51; range 8-88). Two patients required intensive care unit admission. However, no patients died and all were either discharged or were on room air without residual respiratory symptoms by the end of the study period.
