Abstract

To improve our understanding of the migration of sparganum in humans, we report a case of ocular sparganosis having the migratory episode from the muscle cone to the subconjunctiva. A 34-year-old woman was admitted to the Hospital of Anhui Medical University (Hefei, China), in December 2019. She presented with conjunctival hemorrhage and recurrent pain in the left eye. A foreign body was found in the muscle cone of the eye. Two months later, a ribbon-like white material was found under the conjunctiva on slit-lamp examination. A long and slender, actively moving parasite was extracted by surgery. The extracted worm was approximately 8 cm long and 2 mm wide. The worm was whitish, wrinkled, ribbon shaped, and had a slightly enlarged scolex. The worm sample was morphologically identified as a plerocercoid larva (sparganum) of the Spirometra tapeworm. Her conjunctival blood suffusion and eye pain ceased within 1 week after operation. She has been in good health without any symptoms during the 2-year follow-up. A case of ocular sparganosis, in which larval worm migrated from the muscle cone to the subconjunctiva is reported from China.

中国的一例眼球海绵体病:从肌锥到结膜下的移行发作。
为了加深我们对人类眼棘皮病迁徙的了解,我们报告了一例从肌锥到结膜下的眼棘皮病迁徙病例。一名34岁的女性于2019年12月入住安徽医科大学附属合肥医院。她出现结膜出血和左眼反复疼痛。在眼球肌锥内发现异物。两个月后,裂隙灯检查发现结膜下有丝带状白色物质。通过手术取出了一条细长、活动频繁的寄生虫。取出的寄生虫长约 8 厘米,宽约 2 毫米。虫体呈白色、皱褶状、带状,有一个略微增大的鞘膜。虫体样本经形态学鉴定为螺旋绦虫的盘尾幼虫(sparganum)。术后一周内,她的结膜充血和眼痛症状消失。在两年的随访中,她一直健康状况良好,没有出现任何症状。中国报告了一例由幼虫从肌锥移行到结膜下的眼球螺旋体病。
