Inferior rectus muscle ocular cysticercosis: A case report

Abstract

Cysticercosis is a systemic parasitic disease caused by the larval form of cestode Taenia solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The most commonly involved sites include eye, brain, bladder wall, and heart. Ocular cysticercosis can be extraocular or intraocular and may present with varied clinical symptoms. We report the condition in a thirteen year old female child who presented with mild lower lid swelling and diplopia in upgaze, wherein cysticercus cellulosae cyst was found within the mass of the right inferior rectus muscle. It becomes important to report this case because of the relative rarity of the condition these days, unusual site of the cyst and the young age of the patient.

A case of isolated eyelid cysticercosis masquerading as a dermoid cyst: histopathology to the rescue

“…Enzyme Linked Immunosorbent Assay (ELISA) done for Anticysticercal Antibodies in serum help to confirm the diagnosis but negative result does not rule out the cysticercosis. 7 Indirect Hemagglutination Assays are also available, titer of which greater than 1:64 is considered as an indicator of active infection.…”

Extra-ocular Cysticercosis Mimicking Orbital Cellulitis

“…It is endemic in regions with poor sanitation and occurs by ingesting the eggs of Taenia solium from contaminated food and water. 2 Organ systems most commonly involved include eyes, brain, bladder wall, and heart. 2 Ocular cysticercosis can be extra-ocular (in the sub-conjunctival or orbital tissues) or intraocular (in the vitreous, subretinal space or anterior chamber).…”

“…2 Ocular cysticercosis can be extra-ocular (in the sub-conjunctival or orbital tissues) or intraocular (in the vitreous, subretinal space or anterior chamber). 2 A 14-year old boy was brought to the emergency department in a large teaching hospital in north-eastern India with a 2-week history of occasional headaches, repeated episodes of vomiting, and progressive increase in swelling of the left eye, associated with restriction of movements of the eyeball. There was no reported pain, difficulty in vision, discharge or redness of the eyes or eye lids.…”

“…Clinicians should remain aware of the varied signs and symptoms of ocular cysticercosis including acquired strabismus, diplopia, recurrent redness of the eye(s), and proptosis. [2][3][4] Although one or more extra-ocular muscles may be simultaneously involved, there is a propensity for LETTER TO THE EDITOR Extra-Ocular Cysticercosis Mimicking Orbital Cellulitis Figure 1: Proptosis of the left eye at presentation.

“…However, vitreous hemorrhage as preoperative feature or postoperative complication, blindness, or development of neurocysticercosis are also known. 2,5 It is essential that the diagnosis of ocular cysticercosis is considered and appropriate investigations are initiated in a time-critical manner. Early treatment is likely to prevent any long-term or severe damage or development of neurocysticercosis.…”
