最危险的寄生虫感染之一——囊尾蚴病，几乎在世界各地都有发现。纤维素囊尾蚴是猪绦虫猪带绦虫的幼虫阶段，可引起囊尾蚴病。眼眶或眼部囊尾蚴病（OOC）是一种可以避免的失明原因。眼部囊尾蚴病有两种类型：眼内（前房、视网膜下腔或玻璃体）和眼外（眼眶组织或结膜下腔）。在此，我们报告一例罕见的眼外肌囊尾蚴病，表现为右眼内眦附近的孤立的、边界明确的分叶状肿块，并通过抗蠕虫药物和皮质类固醇治疗得到了良好的治疗。诊断肌囊尾蚴病的关键是眼眶成像。尽管囊尾蚴病累及大脑和眼部很常见，但眼外肌囊尾蚴病极为罕见，主要影响年轻人和儿童。眼眶假瘤、特发性肌炎和包虫囊肿是眼囊尾蚴病的一些鉴别诊断。尽早识别和治疗此类疾病以避免严重后果至关重要。公共卫生措施对于根除该地区的这种疾病至关重要。版权所有 © 2024，Tayal 等人。

One of the most dangerous parasite infections, cysticercosis, is found practically everywhere in the world. Cysticercus cellulosae is the larval stage of the swine tapeworm Taenia solium, which causes cysticercosis. Orbital or ocular cysticercosis (OOC) is an avoidable cause of blindness. There are two types of ocular cysticercosis: intraocular (in the anterior chamber, subretinal space, or vitreous) and extraocular (in the orbital tissues or subconjunctival space). Here, we report a rare case of extraocular muscle cysticercosis that presented as a solitary, well-defined lobulated mass near the medial canthus in the right eye and was well managed medically with antihelminthic drugs and corticosteroid therapy. The key to diagnosing myocysticercosis is orbital imaging. Although brain and ocular involvement in cysticercosis is common, extraocular muscle cysticercosis is extremely uncommon and mainly affects young people and children. Orbital pseudotumor, idiopathic myositis, and hydatid cysts are a few differential diagnoses for ocular cysticercosis. It is critical to recognize and treat such illnesses as early as feasible to avoid serious consequences. Public health measures are essential to eradicate this disease in the area.Copyright © 2024, Tayal et al.
