Abstract
Background
Dural relationships and their possible implications on surgical treatment of oculomotor nerve neurinomas are discussed on the basis of surgical experience with two cases.
Materials and methods
We describe two cases with large oculomotor neurinomas that probably arose from the precavernous sinus segment of the nerve. Both tumors were located entirely within the confines of dura or were “interdural.” Operating within the limits set and protection afforded by the dura, the tumors could be excised relatively easily and safely. While the third nerve function recovered completely in one patient, the other continued to have complete third nerve palsy. The duration of follow-up in two cases was 52 and 24 months.
Results and conclusions
Even the intracranial component of large oculomotor neurinoma can be covered entirely by dura. Understanding of the dural relationship can assist in planning and conduct of surgery.
