We herein report a case of recurrent mediastinal cyst infection followed by bacteremia after endobronchial ultrasound-guide transbronchial needle aspiration (EBUS-TBNA). A 65-year-old Japanese male with sarcoidosis presented with 4 L progressive lymph node adenopathy and was diagnosed with mediastinal cyst by EBUS-TBNA. After bronchoscopy, he suffered from a high fever. Chest computed tomography showed enlargement of the 4 L lymph node with low attenuation areas, the elevation of mediastinal fat concentration. Blood cultures were positive for . Antimicrobial agents were administered for a total of 12 weeks, at which point the size of the lymph node was reduced. However, at 5 months after the discontinuation of antimicrobial agents, the mediastinal cyst infection recurred. It is important to conduct careful follow-up because mediastinal cyst infection following ebus-tbna may relapse with conservative treatment without invasive surgery.
我们在此报告一例经支气管超声引导下经支气管针吸活检术（EBUS-TBNA）后复发性纵隔囊肿感染并继发菌血症的病例。一名65岁患有结节病的日本男性出现4L区进行性淋巴结肿大，经EBUS-TBNA诊断为纵隔囊肿。支气管镜检查后，他出现高热。胸部计算机断层扫描显示4L区淋巴结肿大并伴有低密度区，纵隔脂肪浓度升高。血培养结果为阳性。给予抗菌药物治疗共12周，此时淋巴结大小缩小。然而，在停用抗菌药物5个月后，纵隔囊肿感染复发。由于EBUS-TBNA后纵隔囊肿感染在不进行侵入性手术的保守治疗下可能复发，因此进行仔细的随访很重要。
