A case of congenital orbital cyst originating from the common sheath of superior rectus and levator palpebrae superioris muscles.
OBJECTIVE
To assess the clinical and histopathological features of a case of congenital orbital cyst originating from the common sheath of the superior rectus and levator palpebrae superior muscles.


METHODS
Preoperative, peroperative and postoperative characteristics of the described clinical condition in a 37-year-old woman is documented.


RESULTS
The cyst was found to be related with the common sheath of the superior rectus and levator muscles during the surgical intervention and histopathological examination revealed a cystic structure with a lining resembling that of conjunctiva.


CONCLUSIONS
Our findings support the proposal by Rose & O'Donnell who first reported four cases in 1995 suggesting a new group of congenital orbital cysts distinct from dermoid, epidermoid or conjunctival cysts.
