Abstract

A 33-year-old male presented with a rare intracranial oculomotor schwannoma not associated with neurofibromatosis manifesting as an 8-month history of right oculomotor nerve paresis. Neuroimaging examinations revealed a 4-cm mass in the right crural cistern. The tumor was totally removed. The right oculomotor nerve paresis resolved 7 months after surgery. Removal of the oculomotor or trochlear schwannoma usually results in parent nerve paresis, but subcapsular tumor resection in our case probably allowed complete recovery of the nerve function.
