The Prevalence of Azygos Lobe Incidentally Detected on Lung X-ray in Male Police Vocational School Students: A Cross-sectional Study
Abstract
Aim: Azygos lobe (AL) is a rare congenital anomaly that is usually located at the apex of the right lung. It
is mostly asymptomatic and does not require special treatment. However, it should be kept in mind in the
differential diagnosis of lung lesions and its presence should be determined before thoracic operations.
In this study, it was aimed to evaluate the prevalence of AL in a sample of male police vocational high
school students.
Material and Methods: 1623 male police vocational high school students who applied to Erzincan
Binali Yildirim University Faculty of Medicine Chest Diseases Polyclinic between October 1, 2020 and
October 31, 2021 were included in our study. The presence of AL was investigated in the posteroanterior
chest X-ray of the students and the prevalence was calculated. In addition, the regional distribution
of the students according to their place of birth, and other chest deformities detected in the physical
examinations were determined and their relationship with the frequency of AL was investigated. Results: The mean age of 1623 students included in the study was 25.6±2.4. AL was detected in 29 people and the prevalence of AL
was calculated as 1.8%. Although 21 (72.4%) of 29 students with AL were students from the Black Sea and Eastern Anatolia regions, no
significant difference was found between the regions(p=0.101). The most common other chest deformity was pectus excavatum. However,
no significant relationship was found between the frequency of…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 29 participants or records.
