Typical and atypical chest computed tomography manifestations in COVID-19 patients

Abstract

Background High-resolution computed tomography (CT) is the most reliable sensitive noninvasive imaging procedure recommended in the diagnosis, assessment, the severity, and follow-up of coronavirus disease 2019 (COVID-19).It has a qualitative and quantitative role. The COVID-19 Reporting and Data System evaluates the probability of COVID-19 pulmonary involvement, and the corresponding CT severity score, which evaluates the approximate percentage of each of the five lobes’ involvement. Research question We aimed to illustrate chest CT typical and atypical manifestations in COVID-19 patients regarding their age, sex, patients’ symptoms, and CT severity score. Study design and methods We conducted a cross-sectional study on 120 patients more than or equal to 18 years with confirmed COVID-19 infection (PCR positive) during the period from April 2021 to October 2021, who were admitted to Ain Shams University Isolation Hospitals, where all patients’ clinical data and CT chest imaging for these patients will be collected.
