Frequency Of HRCT Findings and Distribution in Lung Parenchyma in Pneumonia

Abstract

Lung’s primary role is to allow the diffusion of gases from the surrounding atmosphere into circulation. Pneumonia and associated spread in the lungs parenchyma is a very common finding in one or both lungs. Objective: To determine the frequency of HRCT findings and distribution in the lung parenchyma in pneumonia patients. Methods: It was a cross-sectional study conducted at a Tertiary Hospital in Lahore, Pakistan in the department of Radiology over five months, from January 2022 to May, 2022. A sample size of 90 patients was taken using a convenient sampling approach from previously published articles. Patients with pneumonia were included in the study after informing a consent. All the data were entered and analyzed using SPSS version 22.0. Results: Results shows that pneumonia is more common in the age of 56-65years (30.0%). It is more common in the patients having a history of smoking 44(48.9%). One of the most prevalent CT findings was ground-glass opacities 55(17.7%). Lung infection dissemination was found to be unilateral in 16(17.8%) patients and bilateral in 74(82.2%). On categorization and parenchymal distribution, lobular pneumonia was more common 77(85.6%). Conclusion: In conclusion, pneumonia is the most prevalent disease among children and older males at the age of 56-65years, having previous history of smoking. The most prevalent observations were lymphadenopathy, ground-glass opacities GGO, and consolidations. Bronchopneumonia findings are more common however, the majority of cases were bilateral than unilateral.
