We describe a Schistosoma haematobium infection with asymptomatic eosinophilia, persistently negative urine microscopy, and late seroconversion (7.5 months) in a traveler returning from Mali. After initial negative parasitological tests, travel history led to diagnostic cystoscopy, allowing final diagnosis with urine microscopy after the bladder biopsy. The patient was successfully treated with praziquantel. Difficulties in making the diagnosis of schistosomiasis in asymptomatic returning travelers are discussed; we propose a trial treatment in these cases.
我们描述了一例从马里旅行返回的无症状嗜酸性粒细胞增多症、尿液显微镜检查持续阴性和晚期血清学转换（7.5 个月）的曼氏血吸虫感染。在最初的寄生虫学检查阴性后，旅行史导致了诊断性膀胱镜检查，在膀胱活检后通过尿液显微镜检查最终确诊。该患者成功接受了吡喹酮治疗。我们讨论了在无症状返回旅行者中诊断血吸虫病的困难，并提出了在这些情况下进行试用治疗的建议。
