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,通常在晚期发现,当疾病如此广泛以至于不再需要根治性手术时。因此,需要较小的侵入性活检技术来建立明确的术前诊断。支气管内超声 (EBUS) 可用于产生淋巴结和支气管附近肺动脉内部的实时图像。我们报告了一例通过EBUS观察到的肺动脉肿块样病变,并通过支气管内超声引导的经支气管针吸活检 (EBUS-TBNA) 从中获得了组织,以确定PAS的诊断。
