Intraretinal cysticercosis

Abstract

A healthy 25-year-old male pork handler presented to a clinic in India with painless vision loss for 6 months in his left eye. Visual acuity was 20/20 in the right eye and light perception in the left. Ultrasound of the left eye showed a retinal detachment with a hyperechoic focus (figure). No parasites were observed in the vitreous or other ocular structures. A still retinal image showed a large cystic space (figure). The patient had been treated with a 3-day course of albendazole 3 months before this visit. CT scan of the brain showed lesions consistent with neurocysticercosis. Video imaging showed the intraretinal motility of the Taenia solium parasite in response to bright light (video).
