A Case of COVID-19 in an Elderly Patient Evaluated by Axial CT Presented with Severe Signs and Symptoms: A Correlation of Severe Hypoxia with Remaining Lung Tissue

Identification of computerized tomography (CT) characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is essential to early diagnosis and treatment of patients and stage the disease according to the appearance of the lung field involvement. The CT chest images of a patient with severe SARS-CoV-2 were collected to assess the CT findings and characteristics. Patchy ground-glass opacities (GGO) were found in some upper lung zones with right upper lung interlobar septal thickening and formation of consolidation throughout the middle and lower zones of the lungs of Crazy Paving pattern type. The remaining lung tissue is directly proportional to the measured oxygen concentration in a severe symptomatic COVID-19 case. These findings are beneficial for early detection and assessment of the severity of SARS-CoV-2.
