, a nontuberculous mycobacterium, is a member of the complex (MAC). This microorganism has recently gained significant notoriety for its association with outbreaks in patients exposed to contaminated heater -cooler devices used during open heart surgeries. We report a case of pulmonary infection in a healthcare worker who presented with cough, low grade fever and weight loss with evidence of a lung mass that was initially thought to be a tumor on CT scan imaging. The patient underwent partial left lung lobectomy and pathology revealed necrotizing granulomas with acid fast bacilli and a culture grew . The patient received combination antimycobacterial therapy according to susceptibility results for twelve months with complete resolution of his symptoms and radiographic findings. Infection Control investigation could not find a source of infection in the hospital where he worked during the last ten years. However, the patient rotated in different hospitals before coming to work at this facility and assisted in surgeries in several operating rooms where the heater-cooler devices in question were used.
非结核分枝杆菌是鸟分枝杆菌复合群（MAC）的成员。这种微生物最近因与心脏直视手术中使用的受污染加热 - 冷却设备接触的患者爆发感染而声名狼藉。我们报告一例医护人员的肺部感染病例，该患者表现为咳嗽、低热和体重减轻，CT扫描显示肺部有肿块，最初被认为是肿瘤。患者接受了左肺部分肺叶切除术，病理显示有坏死性肉芽肿伴抗酸杆菌，培养结果为[具体菌种未给出]。患者根据药敏结果接受了十二个月的联合抗分枝杆菌治疗，症状和影像学表现完全缓解。感染控制调查在他过去十年工作的医院中未发现感染源。然而，该患者在来此机构工作之前曾在不同医院轮转，并在几个使用了相关加热 - 冷却设备的手术室协助手术。
