CTICasesCOVID-19 Organizing Pneumonia with Cystic Change
Imaging findings
An acutely presenting COVID-19 patient has extensive ground glass in an organizing pneumonia pattern, with numerous small holes within the areas of ground glass. The uninvolved lung is normal without emphysema, and the small cystic spaces (possibly dilated small airways or pneumatoceles) occur within the ground glass, some in branching pairs.
Key takeaways
COVID-19 with an extensive organizing pneumonia pattern can show numerous small cystic holes within areas of ground glass, distinct from emphysema, likely representing dilated small airways or pneumatoceles from acute lung injury. This finding was not commonly recognized and is worth watching for as more cases are seen.
