Cysticercosis is a parasitic infection caused by the larvae of the cestode . Ocular parasitosis in humans is well recognized; however, cysticercosis of the optic nerve is rare. Here, we report a case of an adult male who presented with right-sided headache and a gradual loss of vision in the right eye. Optical coherence tomography indicated severe loss of ganglion cells in the right eye. Magnetic resonance imaging showed a predominantly suprasellar cystic lesion thought to represent an arachnoid cyst. We performed a craniotomy to excise the cyst. Histopathological examination of the excised cyst revealed internal living larvae of . After co-administration of praziquantel and albendazole, vision was restored, and the headaches ceased. Vision has since been restored in both eyes. A higher degree of neurocysticercosis suspicion should be maintained for patients living in endemic areas who present with ophthalmic symptoms where the brain scans show cystic lesions.
囊尾蚴病是由绦虫幼虫引起的寄生虫感染。人体眼部寄生虫病已得到充分认识；然而，视神经囊尾蚴病却很罕见。在此，我们报告一例成年男性病例，该患者出现右侧头痛并右眼视力逐渐丧失。光学相干断层扫描显示右眼神经节细胞严重缺失。磁共振成像显示主要为鞍上囊性病变，考虑为蛛网膜囊肿。我们进行了开颅手术以切除囊肿。对切除囊肿的组织病理学检查发现内部有活的幼虫。联合使用吡喹酮和阿苯达唑后，视力恢复，头痛停止。此后双眼视力均已恢复。对于生活在流行地区且出现眼部症状且脑部扫描显示有囊性病变的患者，应保持更高程度的神经囊尾蚴病怀疑。
