This study found a weak, non-significant link between spleen enlargement and lung involvement in COVID-19 patients. Spleen size is not a reliable predictor of pulmonary complications in coronavirus disease 2019.
Area of Science:
- Infectious Diseases
- Radiology
- Pulmonology
Background:
- Coronavirus disease 2019 (COVID-19) impacts multiple organ systems beyond the respiratory tract.
- Splenomegaly (enlarged spleen) is a noted extrapulmonary manifestation of COVID-19.
- The relationship between splenomegaly and lung involvement in COVID-19 remains unclear.
Purpose of the Study:
- To investigate the correlation between spleen size, assessed via CT imaging, and the extent of lung involvement in COVID-19 patients.
- To explore potential prognostic value of splenomegaly in COVID-19 severity.
Main Methods:
- Retrospective cross-sectional study of 1058 symptomatic COVID-19 patients.
- Computed tomography (CT) imaging used to measure spleen size and lung involvement (LI).
- Statistical analysis including Pearson correlation and linear regression.
Main Results:
- Mean spleen size was 9.49 cm; mean LI score was 0.272.
- A marginal positive correlation (r=0.0495) was observed between spleen size and LI.
- Spleen size explained only 0.2% of the variance in LI scores, indicating minimal impact.
Conclusions:
- A statistically non-significant correlation exists between splenomegaly and lung involvement in COVID-19.
- Splenic enlargement may indicate systemic disease but is not a strong independent predictor of lung damage.
- Further research is needed to understand the full implications of splenic involvement in COVID-19.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
