Abstract：
Schistosomiasis is a neglected disease that is prevalent in tropical and subtropical areas. A 20-year-old woman presented to the emergency room with a history of right flank pain and lower abdominal discomfort for one day, which coincided with the onset of menses. The patient did not provide any history of premenstrual hematuria. The physical examination revealed right costovertebral angle tenderness and was otherwise unremarkable. The urinalysis demonstrated a mild increase in red and white blood cells and no ova or parasite. The blood test was normal, except for eosinophilia. A right pedunculated intraluminal urinary bladder mass was detected by the computerized axial tomographic scan and ultrasonography, and after the transurethral resection of the mass, the patient was diagnosed with urinary schistosomiasis. The patient received two doses of oral praziquantel of 1200 mg every 12 h for one day. The cure was confirmed with a one-month post-treatment follow-up that revealed a normal urine microscope and eosinophil count. The S. haematobium infection should be evaluated as a possible cause of urinary bladder lesion in those who have travelled or lived in endemic areas.
摘要：
血吸虫病是一种被忽视的疾病，在热带和亚热带地区普遍存在。一名20岁的妇女出现在急诊室，有一天右侧腹部疼痛和下腹部不适的病史，这与月经的开始相吻合。患者未提供任何经前血尿病史。体格检查显示右侧脊柱角压痛，其他情况不明显。尿液分析显示红细胞和白细胞轻度增加，没有卵子或寄生虫。验血正常,除了嗜酸性粒细胞增多.通过计算机轴向断层扫描和超声检查检测到右侧带蒂的腔内膀胱肿块，经尿道切除肿块后，患者被诊断为泌尿血吸虫病。患者每12小时接受两剂口服吡喹酮1200mg，持续一天。治疗后一个月的随访证实了治愈，结果显示尿液显微镜和嗜酸性粒细胞计数正常。对于那些在流行地区旅行或生活过的人，应将血吸虫感染评估为膀胱病变的可能原因。
