Abstract

A 21-year-old vegetarian male presented to our OPD complaining of pain and protrusion of LE with no diplopia or limitation of movements.

EXAMINATION: BCVA (BE): 6/6. Anterior and posterior segments were normal. Mild proptosis of LE was noted.

An orbital B-scan of LE showed a circular lesion in the superior section, with a hyper-reflective dot like echo suggestive of a scolex. CT scan of orbit showed a circular area of hypo-density with a central hyper-dense lesion suggestive of a scolex in the superior oblique muscle. CT Brain was normal. Blood and stool investigations were normal as well.

Patient was started on Tab. Albendazole 400mg BD and systemic steroids. Symptomatic improvement was noted. Repeated scans showed absence of scolex suggesting resolution.

Cysticercosis is caused by the larval form of a parasite called Taenia solium. Extraocular muscle form is the commonest type of presentation in India. However, isolated involvement of muscle with no neurocysticercosis is rare.
