Congenital orbital teratoma.

Congenital orbital teratoma is a rare tumor that usually presents with unilateral proptosis in a normal full term infant. These tumors are usually confined to the orbit without extension into the intracranial cavity. A few cases with intracranial extension have been reported. We have developed a combined ophthalmological, otolaryngological and neurosurgical approach to deal with this rare tumor when it extends intracranially.
