Summary

Introduction

Respiratory symptoms resulting from the rupture of peribronchial/tracheal cysts are rarely reported. A 31-year-old woman had a history of asthma, hypoplasia of the right upper lobe on computed tomography, and repeated episodes of pneumonia from childhood. She began to experience asthmatic symptoms in the 32nd week of pregnancy and was treated as asthma by her primary physician. After a cesarean was performed under general anesthesia with endotracheal intubation, her respiratory condition and the radiological findings immediately improved, and she was extubated on the first postoperative day She had recurrent dyspnea on the ninth postoperative day. B3 was observed as an ectatic bronchus filled with sputum We speculated that this intrapulmonary cyst ruptured into the airway, with the contents of the cyst flowing into the lower bronchi and obstructing the middle/lower lobes, causing repeated episodes of dyspnea.
