Résumé
Bronchogenic cyst (BC) is a very rare congenital anomaly occurring due to budding of the primitive foregut, and its common location is the posterior mediastinum. BC when diagnosed prenatally can be treated if it is encroaching on the development of lungs. BC has been reported in other locations such as cervical, thoracic, abdominal sites and also as subcutaneous lesions. Omphalocele is a congenital malformation occurring due to a central defect in the abdominal wall with herniation of the viscera. The nonentity documented here was found in a female fetus with 20 weeks of gestational age. The mother was a primigravida who had antenatal ultrasound scan rendering diagnosis of a live fetus having abdominal wall defect with omphalocele. This case is exceptionally rare as the content of omphalocele was BC having a classical wall lined by pseudostratified ciliated columnar epithelium overlying band-like cartilage. The extensive search in the literature did not reveal another similar case.
