Schwannoma of the abducens nerve in the cavernous sinus.
Six cases of cavernous abducens nerve schwannoma have been reported. A new case of a 39 year old female with abducens nerve paresis, exophtalmos, chemosis and headache due to a 1,36 x 2,58 cm cystic right cavernous abducens nerve schwannoma is presented and discussed. The cavernous sinus was opened between the trochlear and ophthalmic nerves. A portion of the tumor capsule adherent to the internal carotid artery was not resected. No deficits were added by surgery. After 30 months of follow up there is no evidence of relapse and only abducens nerve paresis persists.
