Spirometry flow-volume measurement is used routinely in the outpatient setting to rule out obstructive lung diseases. Biphasic flow-volume loop is a classic presentation of unilateral bronchial stenosis due to multiple etiologies and it should raise clinical suspicion. Granulomatosis with polyangiitis (GPA) is a systemic inflammatory condition with pulmonary manifestations that may be infiltrative (e.g., pneumonia), hemorrhagic, and may rarely cause bronchial stenosis. Herein, we present a case of GPA-related, bronchial obstruction that caused biphasic flow-volume loop along with a literature review.
肺量计流量-容积测量在门诊环境中常用于排除阻塞性肺疾病。双相流量-容积环是多种病因导致的单侧支气管狭窄的典型表现，应引起临床怀疑。肉芽肿性多血管炎（GPA）是一种具有肺部表现的全身性炎症性疾病，其肺部表现可能为浸润性（如肺炎）、出血性，且很少会导致支气管狭窄。在此，我们报告一例与GPA相关的支气管阻塞病例，该病例导致了双相流量-容积环，并进行文献综述。
