Orbital teratoma: case report and management review.

We present a case of benign mature orbital teratoma in a neonatal boy that involved the chiasmal area and cavernous sinus and displaced the nasopharynx. Visual potential was deemed to be good. Because of the chiasmal involvement, complete surgical resection, which would have compromised his visual function, was considered inadvisable. A debulking procedure, mainly of the cystic parts of the tumor, was performed. The patient remains stable at 3 years of age, with no further growth of the tumor and good vision in the affected eye.
