Schistosomiasis is a widely prevalent disease in the world and usually involves the gastro-intestinal and urinary tract. The involvement of the female genital tract has been well-established in S. haematobium infections and is rare with S. japonicum infections. This case involves a Filipino female who was admitted to the University Hospital Kuala Lumpur for right iliac fossa pain and was diagnosed initially as acute appendicitis. Ultrasound showed a multi-septated pelvic cyst leading to a provisional diagnosis of ovarian torsion. Intraoperatively a right parovarian cyst was detected and removed. Histology revealed a congested cyst wall with areas of haemorrhage with several viable and calcified eggs of S. japonicum measuring 85 microns x 62 microns. Within the cystic cavity blood admixed with eggs were seen. Confirmation was carried out by using the indirect haemagglutination (IHA) test. This is a first report of upper genital schistosomiasis mimicking an ovarian tumour.
血吸虫病是一种在世界范围内广泛流行的疾病，通常累及胃肠道和泌尿道。在埃及血吸虫感染中，女性生殖道受累已得到充分证实，而在日本血吸虫感染中则较为罕见。该病例为一名菲律宾女性，因右下腹疼痛入住吉隆坡大学医院，最初被诊断为急性阑尾炎。超声显示一个多房性盆腔囊肿，初步诊断为卵巢扭转。术中发现并切除了一个右侧卵巢冠囊肿。组织学检查显示囊肿壁充血，有出血区域，可见数个存活和钙化的日本血吸虫卵，大小为85微米×62微米。在囊腔内可见血液与虫卵混合。通过间接血凝试验（IHA）进行了确诊。这是首例模仿卵巢肿瘤的上生殖道血吸虫病报告。
