Isolated Oculomotor Nerve Palsy Caused by Cavernoma of the Midbrain

Abstract

Cavernoma of the midbrain (CM) is being diagnosed more and more often with the increasing use of MRI. We report a 46-year-old woman who presented with sudden-onset isolated oculomotor nerve palsy (ONP). Moreover, we discuss the radiological changes and different management options. We recommend that CM be included in the differential diagnosis of sudden-onset ONP, especially in normotensive young patients without other vascular risk factors.
