COVID-19 pneumonia - incidental finding in asymptomatic patient

Case contributed by Jörgen Strömberg


Routine CT thorax/abdomen follow up for oncologic treatment of a GI tract cancer. No known metastases. The patient was clinically well.

Patient Data

Age: 60 years
Gender: Female

Peripheral ground glass opacifications with diffuse delineation in the left upper lobe, not present on previous exams. No other parenchymal changes. No lymphadenopathy, no pleural effusions.

Case Discussion

This incidental finding was reported to the clinician as suspicious for COVID-19, and subsequent PCR testing confirmed the diagnosis.

The case serves to illustrate that even patients presenting with no symptoms may have changes on chest CT. This is in keeping with previous reports, e.g. from the Diamond Princess, where 54% of asymptomatic but PCR confirmed cases proved to have CT findings 1.
