Trochlear nerve enhancement on three-dimensional magnetic resonance imaging in Fisher syndrome

Am J Ophthalmol. 1998 Aug;126(2):322-4. doi: 10.1016/s0002-9394(98)00161-5.


Purpose: To examine the lesion associated with external ophthalmoplegia in Fisher syndrome using three-dimensional magnetic resonance imaging (3-D MRI).

Method: Case report. A 65-year-old woman with Fisher syndrome was investigated by gadolinium-enhanced 3-D MRI.

Result: The extramedullary portion of the left trochlear nerve was enhanced.

Conclusion: Contrast-enhanced 3-D MRI revealed that the lesion responsible for the external ophthalmoplegia in Fisher syndrome is located in the extramedullary portion of the trochlear nerve.
