Abstract

Typical computed tomography (CT) findings in COVID-19 infection include bilateral, peripheral ground-glass opacities, with or without consolidations, often showing lower lobe and posterior predominance and sometimes accompanied by “crazy-paving” pattern. A spectrum of post-COVID pulmonary sequelae has been reported in interstitial lung disease (ILD) literature. However, emphysema-like changes are rarely described and usually occur in the presence of other risk factors for chronic obstructive pulmonary disease. Herein, we describe a case of a young female never-smoker with persistent paraseptal lucencies mimicking emphysema, thought to be related to prior COVID-19 infection or post-viral pneumonia. Description A 20-year-old-female never smoker with moderate persistent asthma, morbid obesity and prior COVID-19 infection was referred to pulmonary clinic for evaluation of abnormal chest CT. She denied secondhand smoking, vaping, or environmental/occupational exposures. There was no personal or family history of emphysema, alpha-1 antitrypsin deficiency, surfactant disorders, or connective tissue disease. She reported a COVID-19 infection three years prior and a subsequent hospitalization one year later for viral pneumonia and asthma exacerbation, transiently requiring oxygen supplementation. During that hospitalization, contrast-enhanced CT chest demonstrated left lower lobe consolidation and paraseptal emphysema. No prior imaging was available. She subsequently returned to…

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
