The Relationship among Splenomegaly, Lung Involvement Patterns, and Severity Score in COVID-19 Pneumonia.

INTRODUCTION: The disease caused by the novel coronavirus (COVID -19) is a vital public health problem that has now affected approximately 68,037,473 people and caused 1,552,802 deaths around the world. We aimed to correlate the frequency of the lung involvement patterns, the segmental distribution of lung infiltration, and TLSS in COVID-19 pneumonia patients with and without splenomegaly. MATERIAL AND METHODS: This retrospective study included patients admitted to Yunus Emre State Hospital Emergency, Internal Medicine and Infectious Disease Departments between March 11, 2020, and June 10, 2020, and diagnosed with COVID-19 by PCR test with a throat and nasal swab. The thoracic and upper abdomen CTs and the clinical and demographic features of the patients were analyzed at the time of initial diagnosis. RESULTS: Consolidation (group 1 - 18 (47%), group 2 - 69 (28.2%); P = 0017), crazy pavement pattern (15 (39.5%), 42 (17.1%); p = 0.001), pleural band formations (24 (63.2%), 87 (35.5%); p = 0.001), interlobular septal thickening (23 (60.5%), 79 (32.2%); p = 0.001), and sequelae of secondary tuberculosis (4 (10.5%), 8 (3.3%); p = 0.039) were more frequent in the patient with splemomegaly. The total lung severity score was high in the group with splenomegaly (7.32 ± 6.15, 3.69 ± 5.16; p = 0.001). CONCLUSION: Consolidation, interlobular septal thickening, tuberculosis sequela, pleural band, and crazy pavement patterns were frequent in the COVID-19 pneumonia patients with splenomegaly. The most frequently affected segment was the superior segment of the right lower lobe. TLSS was higher in the COVID-19 pneumonia patients with splenomegaly.

Chest computed tomographic findings of patients with COVID-19-related pneumonia.

BACKGROUND: In December 2019, pneumonia cases of unknown cause were announced in Wuhan, China. The causative agent of pneumonia was identified as coronavirus 2 (SARS-CoV-2), and the disease was named coronavirus disease 2019 (COVID-19). PURPOSE: To evaluate the usefulness of computed thoracic tomography (CT) and postero anterior (PA) thoracic radiography in patients with COVID-19. MATERIAL AND METHODS: Between March and June 2020, the patients who arrived at our hospital with suspicion of COVID-19 were retrospectively analyzed. Thorax CT findings of the 281 patients (142 females and 139 males; age range 3-91 years) with positive PCR tests were evaluated. Lesions in the lung parenchyma were examined according to their number, localization, and distribution. PA chest radiograms were classified into two groups, positive and negative for the lung parenchymal lesions. RESULTS: Of the total 281 patients with PCR-positive COVID-19, CT examinations were normal in 107 (38.1%), and positive CT findings for pneumonia were found in 174 patients (61.9%). Bilateral involvement was observed in 100 (57.5%) of the 174 patients with positive CT findings, and unilateral involvement was observed in 74 (42.5%) of them. According to the localization of the lesions, peripheral subpleural distribution occurred in 160 of the 174 patients (91.9). The most common lesion was the ground glass opacities (GGO). In 77 of 281 PCR-positive patients (27.4), pulmonary lesions were found on PA chest radiograms. CONCLUSION: The presence of bilateral posterior subpleural GGO, nodule, and consolidation in thoracic CT are significant in terms of COVID-19 pneumonia.
