Summary: | Aim: Our study aimed to evaluate the atypical CT findings and concomitant pathologies of COVID-19 pneumonia and clinical and
laboratory findings and compare them with typical CT findings.
Materials and Methods: A total of 69 patients were diagnosed with COVID-19, 14 of which were atypical (20.2%), and 55 of which were
typical (79%) chest computed tomography (CT) findings. CT images and clinical and laboratory data of patients with atypical findings
were retrospectively analyzed. Lesions of the typical and atypical group and CT severity scores were compared.
Results: Atypical CT findings were centrilobular nodule, tree in bud, pleural effusion, lobar/segmental consolidation, bronchiectasis,
pulmonary embolism, and mosaic attenuation by typical lesions with ground-glass opacity with/without consolidation. CT severity score
was significantly higher in the atypical group (p <0.001). CRP, procalcitonin, the neutrophil rate increased, and the lymphocyte count
decreased in patients with a high CT severity score. Comorbidity was common in the atypical group (50%).
Conclusion: High CT severity score and widespread lung involvement of the patient group with atypical CT findings may be due to
disease progression or other concomitant diseases. Atypical lesions accompanying typical lesions may cause false negativity in
reporting. As radiologists' experience with COVID-19 pneumonia increases, it may improve that they categorize these images as typical
or atypical |
