APRIL 17, 2014

Neurocysticercosis is the clinical syndrome of neurologic symptoms secondary to infection with the larval form of tapeworm Taenia solium. While brain parenchymal cystic lesions are the most common form and see in over 60% of patients, extra-parenchymal disease can occur in the intraventricular system, subarachnoid space, spinal cord and less often the eye (1). Ocular cysticercosis occurs in 1-3 percent of overall cases, and lesions frequently localize to the extraocular muscles, often with extension to intraocular structures (2). While some cases are asymptomatic, the symptoms of ocular involvement can include proptosis, ptosis, diplopia, and restriction of motility. Ultrasound or non-contrast CT can often visualize the cyst and scolex and confirm diagnosis.
