ABSTRACT
Background: Pulmonary involvement is the most common systemic involvement in covid infection. The objective of the study was to evaluate the thoracic manifestations of COVID-19 positive cases. Methods: Patient’s record files who have undergone CT chest imaging in Radiology Department, BPKIHS during the period of the study was reviewed and relevant information was entered into SPSS and analysed. Results: Out of 80 patients, 7.5%(6) patients had completely normal CT finding. Out of 74 cases, 89.2 % (8) cases showed multiple lesions. Fifty percentage (37) of lesions were peripheral only, 4.1 % (3) central only and 45.9% (34) both central and peripheral. GGO and consolidation were noted in 98.6 % (73) and 60.8 %(45) respectively and both in 59.46% (44). Crazy paving, microvascular dilatation sign, vacuolar sign, subpleural line, subpleural transpatent line, halo sign, reverse halo sign, air bronchogram, bronchial dilatation and bronchial distortion were observed in 36.5% (27), 79.7%(59) 28.4% (21) ,33.8% (25) and 18.9 % (14), 17.6% (13),10.8% (8) , 60.8% (45), 29.7 % (22) and 16.2% (12) respectively. Pleural effusion, pleural retraction, pleural thickening, pericardial effusion, lymphadenopathy were noted in 14.9% (11), 9.5% (7), 12.2% (9), 4.1% (3) and14.9% (11) respectively. Mean CTSS was 8.62±5.96. Consolidation, crazy paving, microvascular dilatation sign, vacuolar sign,, air bronchogram, bronchial dilatation, bronchial distortion showed significant association with CTSS grading. Lower lobes were predominantly affected. Conclusion: Various pulmonary and extrapulmonary findings are seen in COVID pneumonia and evaluation of these findings helps in diagnosis and possibly management of the patients.
