Objective:
Bronchogenic cysts are rare congenital abnormalities, and usually asymptomatic until adulthood. We present a fetus prenatally diagnosed with a bronchogenic cyst, experiencing compression symptoms immediately after birth and underwent thoracoscopic surgery at 14 days old.
Case Report:
A 33-year-old primigravida had a suspicion of fetal tracheal cyst. Prenatal ultrasound scan revealed a cyst near the trachea at 23 weeks' gestation. Fetal MRI defined a cystic lesion in the upper mediastinum, displacing surrounding vessels. A 3,940 g girl was delivered vaginally at 38 weeks' gestation. Shortly after birth, she developed respiratory distress, and imaging revealed a mediastinal cyst compressing the trachea and esophagus. The cyst was successfully removed through video-assisted thoracoscopic surgery at 14 days old, and pathology confirmed it as a bronchogenic cyst. Follow-up images demonstrated well-aerated lungs. At present, this 1-year-old girl develops normally without respiratory symptoms.
Conclusion:
Early detection in utero, accurate diagnosis, and timely management are crucial for bronchogenic cysts in neonates.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
