WE REPORT THE case of an infant with a mature teratoma of the lateral
wall of the cavernous sinus. A complete excision of the tumor was achi
eved. There was no evidence of recurrence at 1-year follow-up examinat
ion. Intracranial teratomas and the anatomy of the lateral wall of the
cavernous sinus are briefly reviewed. To our knowledge, this is the f
irst case of a teratoma confined to the cavernous sinus.
