title: [Intrapulmonary bronchogenic cysts].
abstract: Bronchogenic cysts are commonly found in the mediastinum, but occasionally in lung parenchyma. We report 3 patients with intrapulmonary bronchogenic cysts. A female presented back pain and a large cystic lesion with an air-fluid level on chest X-ray and computed tomography (CT). Another female was asymptomatic. A well-defined round mass with soft tissue intensity on magnetic resonance imaging (MRI) was found. A girl with repeated pulmonary infection and treatment in hospital for several years presented pulmonary infiltrate, air-fluid level, and oval linear shadow on X-rays. All patients underwent lobectomy because of the size and the non-anatomical location of their lesions. Definite diagnosis on their lesions was determined by pathological study. Several small communications between the cyst and adjunctive parenchyma was found in the symptomatic girl, while the cyst was isolated from surrounding parenchyma in the asymptomatic female. We suggest symptoms and various presentations on imaging modalities in patients with intrapulmonary bronchogenic cysts might relate to the amount of original communication between their cysts and native lung.
