Persistent residual lung abnormalities as final outcome in recovered severe COVID-19 pneumonia with lung function abnormalities in spirometry: Pulmonologist and radiologist perspective

Abstract

Coronavirus-related (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) global pandemic has caused significant mortality and morbidity globally in the last 3 years. In the present case report, a 51-year-old man presented in the outdoor unit for shortness of breath on exertion with a history of severe coronavirus disease-2019 (COVID-19) pneumonia resulted in acute respiratory distress syndrome with hospitalisation in the intensive care unit 1 year back and required high-flow nasal cannula (HFNC) with noninvasive ventilatory support (NIV) for 2 weeks. He was offered oxygen supplementation at home with antibiotics for 3 months and there was no requirement of oxygen and some respiratory symptoms even after 1 year. His high-resolution computed tomography thorax documented at 1 year of discharge from the hospital revealed typical interstitial opacities labelled as persistent residual lung abnormalities (RLAs) that are predominantly reticular and linear opacities in peripheral parts of lungs without honeycombing within typical pleural-based areas with parenchymal bands and minimally altered lung architecture and preserved lung volume.
