A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. Diagnosis of schwannoma was confirmed from the specimen obtained by endobronchial ultrasound-guided transbronchial needle aspiration. She underwent tumorectomy due to the possibility of obstructive pneumonia. Pathology diagnosis from the surgical specimen was also schwannoma. Endobronchial ultrasound-guided transbronchial needle aspiration and findings with endobronchial ultrasonography might be helpful in the diagnosis of intrapulmonary schwannoma.
一位 47 岁女性因肺部肿瘤到我院进一步检查。胸部 CT 显示 S2 邻近右上叶支气管处有一个 2.4cm 的类圆形、边界清楚的结节。支气管内超声显示边界清楚的低回声肿瘤，伴有回声包膜和后方声学增强。支气管内超声引导经支气管针吸活检获得的标本证实为神经鞘瘤。由于可能发生阻塞性肺炎，她接受了肿瘤切除术。手术标本的病理诊断也是神经鞘瘤。支气管内超声引导经支气管针吸活检和支气管内超声检查结果可能有助于肺部神经鞘瘤的诊断。
