Abstract :
Cysticercosis, caused by the larval form of the pork tapeworm Taenia solium is potentially harmful disease
with a variable clinical manifestation. 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 case of extraocular cysticercosis in a 20 year old female presented with right
exotropia, head tilting and painful right eye. CT-scan of right orbit showed bulky medial rectus with
multiple ring enhancing lesions within the muscle, suggestive of cysticercosis. It becomes important
to report this case because of the relative rarity of the condition, unusual site of the cyst i.e atypical
involvement of medial rectus and the young age of the patient.
