title: Orbital Conjunctival Cyst Associated With the Superior Rectus-Levator Muscles: A Clinicopathologic Study.
abstract: A 55-year-old woman had a right orbital cyst detected incidentally on radiographic imaging. The patient's symptoms were mild and included intermittent pain and vertical diplopia; the patient was not aware of any visual decline. There was a palpable mass beneath the superior orbital rim. Radiographic imaging revealed a well-demarcated cystic lesion in the right superior orbit between the levator palpebrae superioris and superior rectus muscles. The mass was completely excised via a transconjunctival approach. Histopathologic evaluation disclosed a conjunctival cyst lined by nonkeratinized squamous epithelium with scattered, rare goblet cells. This case combined with 5 other similar reported cases suggests that an intermuscular cyst located in the superior rectus-levator complex is most likely of congenital embryonic conjunctival origin.
