Pulmonary artery sarcoma (PAS) is a rare tumor that is often detected at an advanced stage, when disease is so widespread that a radical surgical procedure is no longer indicated. Therefore, less invasive biopsy techniques are required to establish a definitive preoperative diagnosis. Endobronchial ultrasound (EBUS) is useful for producing real-time images of both lymph nodes and the interior of pulmonary arteries adjacent to the bronchi. We report a case with masslike lesions in the pulmonary artery that were observed by EBUS and from which tissue was obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to establish a diagnosis of PAS.

:肺动脉肉瘤(PAS)是一种罕见的肿瘤,通常在晚期阶段被发现,这是因为疾病如此广泛以至于不再需要进行彻底的外科手术。因此,需要较少的侵入性活检技术来确定明确的术前诊断。支气管内超声(EBUS)可用于生成淋巴结和邻近支气管的肺动脉内部的实时图像。我们报道了一例EBUS观察到的肺动脉肿块样病变,并通过支气管内超声引导下经支气管穿刺针抽吸术(EBUS-TBNA)从中获得组织以建立PAS的诊断。
