Tracheobronchial schwannomas are rare diseases. Common signs and symptoms of this tumor include cough, wheezing, and dyspnea. In contrast, pneumothorax is an exceptional presentation. This study reports the first case of bronchial schwannoma presenting with pneumothorax. A 79-year-old woman was diagnosed with pneumothorax by chest radiography. Chest computed tomography unexpectedly revealed a tumor occluding the right main bronchus. Following the pathological diagnosis of bronchial schwannoma, the patient underwent thoracoscopic tumor enucleation. The airway lumens are consequently secured postoperatively. We reviewed the literature and discussed the mechanisms and treatment options for bronchial benign tumor-associated pneumothorax. Pneumothorax should be aware of a rare presentation of non-malignant tracheobronchial tumors.
气管支气管神经鞘瘤是罕见疾病。该肿瘤的常见体征和症状包括咳嗽、喘息和呼吸困难。相比之下，气胸是一种特殊表现。本研究报告了首例以气胸为表现的支气管神经鞘瘤病例。一名79岁女性经胸部X线检查诊断为气胸。胸部计算机断层扫描意外发现一个肿瘤阻塞右主支气管。在病理诊断为支气管神经鞘瘤后，患者接受了胸腔镜肿瘤摘除术。术后气道管腔得以确保。我们回顾了文献并讨论了支气管良性肿瘤相关气胸的机制和治疗选择。气胸应被视为非恶性气管支气管肿瘤的一种罕见表现。
