Discussion
Congenital cystic lesions of the lung parenchyma have similar embryogenesis to duplication cysts. Primitive foregut origin cysts include bronchogenic cysts, duplication cysts, enterogenic cysts, neurenteric cysts, and bronchopulmonary cysts. 3
Mediastinal cysts in children are generally symptomatic course. Depending on GID cysts’ location, symptoms such as chest pain, shortness of breath, cough, asthma-like symptoms, hemoptysis, cyanosis, vomiting, difficulty swallowing, weight loss, hematemesis and melena can be observed.3 Rare duplication cysts were reported as three cases in a total of five years in a series, and only one of them was reported to be a thoracic cyst.4,5 In addition to chest radiography, computed tomography, and magnetic resonance images, fluoroscopy helps in diagnosis.6 Treatment is total excision of the cyst. If the cyst is related to the gastrointestinal system, this relationship should be eliminated. Even if GID cysts are asymptomatic, they should be surgically removed because of the mass effect and risk of malignancy.7 In our case, a second operation decision was made as a result of fluoroscopy, and the diagnosis of the thoracic GID (jejunal) cyst was confirmed as a result of repeated operations. Syed et al.8 reported a rare jejunal duplication cyst with obstruction. Our case is a jejunal duplication cyst in the thorax that does not cause bowel obstruction.
