Pulmonary embolism (PE) is a serious condition that often poses a diagnostic challenge. We report a case of a 57-year-old man with tobacco dependence who presented with multiple trauma, with chest imaging findings concerning for malignancy. While performing bronchoscopy with endobronchial ultrasound (EBUS), an echogenic material was incidentally found in the left pulmonary artery. Computed tomography pulmonary angiography (CTPA) was immediately obtained and confirmed the diagnosis of PE. This case illustrates the utility of routine pulmonary artery examination during EBUS procedures in patients at risk of PE and the importance of prompt management including confirmation with CTPA.
肺栓塞（PE）是一种严重疾病，常常带来诊断挑战。我们报告一例57岁有烟草依赖的男性，其因多处创伤就诊，胸部影像学检查结果提示有恶性肿瘤可能。在进行支气管镜检查并使用支气管内超声（EBUS）时，偶然在左肺动脉发现一种回声物质。随即进行了计算机断层扫描肺动脉造影（CTPA），确诊为肺栓塞。该病例说明了在有肺栓塞风险的患者进行EBUS操作时常规检查肺动脉的作用，以及包括通过CTPA确诊在内的及时处理的重要性。
