Bronchogenic Cyst with Atypical Radiological Appearance and Localization, Case Report

Abstract

Bronchongenic cysts, a common bronchopulmonary malformation, are benign lesions that develop as a result of abnormal budding during the embryonic phase. They are usually located in the trachea, and the main bronchi or in the mediastinum around the esophagus. However 15-20% of them may be located in the lung parenchyma, mainly in the lower lobes. Although some of these cysts are asymptomatic, they might cause symptoms due to pressure on the respiratory tract or repeating infections. Bronchongenic cysts are usually found incidentally in routine lung graphics and they appear as well-defined, non-calsified, oval or round, homogeneous densities close to the main airway. It is treated via surgical excision. In this article, we present the case of a 15-year-old patient with symptoms of repeating lung infection and chronic cough. Thoracic CT revealed atypical radiological cavitary lesion located in the upper lobe of the left lung; bronchoscopy showed an increase in the diameter of the lingular segment bronchus in the left upper lobe extending directly to the cavity and the surgical pathology reports identified bronchongenic cysts.
