Abstract
We report the case of a solitary meningioma infiltrating the trochlear nerve, the
first in a patient without a neurocutaneous disorder or cavernous sinus involvement.
The patient presented with diplopia was found to have a focal enhancing mass encompassing
the trochlear nerve. Following surgical resection, pathological examination showed
meningioma infiltrating the nerve itself, demonstrated on the included pathology images.
A review of the literature and discussion of meningiomas infiltrating cranial nerves
are included.
