Abstract
Background: Pulmonary emphysema is divided into 3 major subtypes at autopsy: centrilobular, paraseptal, and panlobular emphysema. There is also a fourth type called paracicatricial emphysema which is described in only some literatures .These subtypes can be defined by visual assessment on computed tomography (CT). This study aimed to provide a baseline on the common CT patterns of pulmonary emphysema in Ethiopia sinceno previous studies were done.
Materials and Methods: In this study, CT scan images of 62 patients were reviewed to determine CT patterns of emphysema in our institutionfrom December 2018 to August 2018. The medical records and the CT reports were reviewed for demographic parameters and clinical information.
Results: The mean age of the 62 individuals studied was 58 ± 15 years. There were 42 males and 20 females. The most common CT pattern was centrilobular emphysema seen in 34(54.8%), followedparacicatricial and paraseptal accounting for 15(24.2%) and 6(9.7%) of cases, respectively. Centrilobular emphysema was the commonest subtype associated with smoking. It involved predominantly the upper lobes. RUL or LUL were involved in 100% (34/34) cases of centrilobular emphysema.
Conclusion:centrilobular emphysema remains the most common among the CT patterns of emphysema and it is the most smoking related type of emphysema. Paracicatricialemphysema which was not mentioned in most literatures is the second most common in our set up which indicate the increased prevalence of pulmonary infections.This study highlighted the need for further study to determine the burden of smokng and pulmonary infections at community setting.
