Strongyloides stercoralis is an intestinal parasite in humans. Infected patients may be asymptomatic or have mild to moderate abdominal symptoms. It may spread to the lungs and, finally, disseminate in the immunocompromised patient. S. stercoralis is an important cause of severe pulmonary infection and death in many areas of the world. Here we describe an 87-year-old man with S. stercoralis pulmonary hyperinfection. He had respiratory failure with severe abdominal distention. Chest x-ray showed infiltration over the right upper lung field. Papanicolaou stain of sputum demonstrated the rabditiform larvae of S. stercoralis. Stool examination revealed S. stercoralis larvae and eggs. He received two courses of albendazole treatment, but died 5 weeks after admission from Gram-negative bacteremia. This case is a classic presentation of the S. stercoralis pulmonary hyperinfection syndrome.
粪类圆线虫是人类肠道寄生虫。受感染患者可能无症状，或有轻度至中度腹部症状。它可能扩散至肺部，最终在免疫功能低下的患者中播散。在世界许多地区，粪类圆线虫是严重肺部感染和死亡的重要原因。在此，我们描述一名87岁患有粪类圆线虫肺部重度感染的男性患者。他出现呼吸衰竭并伴有严重腹胀。胸部X线显示右上肺野浸润。痰液巴氏染色显示粪类圆线虫杆状蚴。粪便检查发现粪类圆线虫幼虫和虫卵。他接受了两个疗程的阿苯达唑治疗，但入院5周后死于革兰氏阴性菌血症。该病例是粪类圆线虫肺部重度感染综合征的典型表现。
