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.
