Endoscopic ultrasonography with high-frequency ultrasonic beams allows detailed study of the gastrointestinal wall structures and the surrounding Tissues. Moreover most echoendoscopes carry a biopsy channel for biopsy or cytologic puncture guided by endoscopic ultrasonography. We present a patient with a tumor in the posterior mediastinum in whom conventional diagnostic techniques failed to obtain speciments for cytologic evaluation. Transesophageal fine needle aspiration guided by endoscopic ultrasonography confirmed the diagnosis of lung cancer consisting of adeno and small cells in this patient. Transesophageal fine needle puncture guided by endoscopic ultrasonography might become a valuable aid for the diagnosis of tumor masses in the posterior mediastinum.
高频超声束的内镜超声检查能够详细研究胃肠道壁结构及周围组织。此外，大多数超声内镜带有活检通道，可用于在内镜超声引导下进行活检或细胞学穿刺。我们报告一例后纵隔肿瘤患者，传统诊断技术未能获取用于细胞学评估的标本。经内镜超声引导下的经食管细针抽吸术确诊该患者为腺癌和小细胞癌组成的肺癌。经内镜超声引导下的经食管细针穿刺术可能成为诊断后纵隔肿瘤肿块的一项有价值的辅助手段。
