Pathophysiology and Imaging Findings of COVID-19 Infection: An Organ-system Based Review

Acad Radiol. 2021 May;28(5):595-607. doi: 10.1016/j.acra.2021.01.022. Epub 2021 Feb 4.

Abstract

Background: COVID-19 commonly presents with upper respiratory symptoms; however, studies have shown that SARS-CoV-2 infection affects multiple organ systems. Here, we review the pathophysiology and imaging characteristics of SARS-CoV-2 infection in organ systems throughout the body and explore commonalities.

Objective: Familiarity with the underlying pathophysiology and imaging characteristics is essential for the radiologist to recognize these findings in patients with COVID-19 infection. Though pulmonary findings are the most prevalent presentation, COVID-19 may have multiple manifestations and recognition of the extrapulmonary manifestations is especially important because of the potential serious and long-term effects of COVID-19 on multiple organ systems.

Keywords: ACE2; COVID-19, SARS-CoV-2; cytokine storm; imaging; inflammation; thrombosis.
