Isolated trochlear nerve palsy secondary to dural carotid-cavernous sinus fistula.
Ophthalmoplegia associated with dural carotid-cavernous sinus fistula typically involves the third, fourth, and sixth cranial nerves. Occasionally, isolated palsy of the oculomotor or abducens nerve is noted. We report a patient with bilateral dural carotid-cavernous sinus fistulas who presented with an isolated trochlear nerve palsy.
