BACKGROUND
An azygos lobe of the lung is a rare congenital venous malformation. It is usually detected using a chest X-ray, but computed tomography can also be used in selected cases for advanced examination and differential diagnosis. An azygos lobe is observed in high-resolution computed tomography images by 1.2%. We explored the prevalence of an azygos lobe using computed tomography at our hospital.
MATERIAL and METHODS
Computed tomography withdrawn by any reason was retrospectively evaluated using a picture archiving and communication system between September 2012 and November 2013 at Dörtyol State Hospital.
RESULTS
By examining thoracic computed tomography, the incidence of azygos lobe was found to be 1.54%. The incidence in woman and man was 1.39% and 1.64% respectively.
CONCLUSION
The frequency of an azygos lobe detected on performing computed tomography imaging was higher than that reported in the literature.
