Mediastinal and retroperitoneal transdiaphragmatic bronchogenic cyst with gastric mucosa

Abstract Background Congenital cystic lung lesions are rare lung malformations. They are mostly diagnosed by a routine antenatal ultrasound scanning. Clinical symptoms ranging from asymptomatic condition to life-threatening course. Case and outcomes We presented a case of congenital cystic lung malformation, the case demonstrated a 20- month- old boy who was reported to our hospital because he was diagnosed prenatally with a right-sided cystic lung mass. He was asymptomatic. A diagnosis of mediastinal retroperitoneal bronchogenic cyst was made radiologically. He underwent a successful right thoracotomy and the transdiaphragmatic cystic mass was completely resected. Histologic examination revealed bronchogenic cyst with gastric mucosa. Conclusion Early diagnosis improves outcomes in infants with congenital cystic lung anomalies. Surgical management is the treatment of choice for congenital cystic lung malformations.
