Abstract:
Cysticercosis results in humans when infected with the larval stage of taenia solium which is called cysticercus cellulosae. The target organs usually involved are the brain, eyes, spine, and skeletal muscles. The ocular form of cysticercosis can affect the intra-ocular structures or involve the orbital adnexa. Intraocular involvement is relatively common and is readily diagnosed owing to its obvious visibility on a basic slit-lamp examination, however, affection of orbital adnexa is infrequent. Moreover, solitary involvement of one of the extraocular muscles is rare and difficult to diagnose as it presents with a spectrum of non-specific symptoms. We report a rare case of orbital cysticercosis with a solitary left superior rectus muscle involvement, who presented with recurrent on and off lid swelling extending for two years with double vision and restriction of downward gaze.
摘要:
当感染了称为猪囊尾蚴的幼虫期时,囊虫病会导致人类。通常涉及的目标器官是大脑,眼睛,脊柱,和骨骼肌。囊虫病的眼部形式可影响眼内结构或累及眼眶附件。眼内受累相对常见,由于其在基本裂隙灯检查中的明显可见性,因此易于诊断。然而,轨道附件的影响是罕见的。此外,单独受累的眼外肌之一是罕见的,难以诊断,因为它表现出一系列非特异性症状。我们报告了一例罕见的眼眶囊虫病,伴有孤立的左上直肌受累,患者反复出现眼睑肿胀,持续两年,具有双重视力和向下凝视的限制。
