Evaluation of Size of Thymus and its Relationship with CT Severity Score in Patients having CT Signs for COVID 19 Virus Disease in the Age Group of 20-40 Years: A Study of 100 Cases

Aims: To measure the size of thymus and find the relationship of thymus gland enlargement with CT severity score on computed tomography. Methods and Material: In this study, we have collected computed tomography scans of 100 patients who showed CT signs for COVID 19 virus disease (CORADS 5). The age group for cases included in our study was 20-40 years. Statistical analysis used: Chi square test. Results: In a study of 100 cases, we found that there is a significant association between size of left lobe of thymus and CT severity score. Conclusion: In COVID 19 patients, thymus enlargement was frequent with patients having higher CT severity score. This may be due to increased T lymphocytes production that appears due to virus induced lymphopenia. Thus we know a relationship between increased thymus size and increased CT severity score in COVID 19 virus disease patients.
