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.
