Description This is a 15-yo-girl who experienced headache and imbalance leading to an MRI which showed a left sided cerebellopontine angle (CPA) tumor. Because of involvement of the left brainstem/cerebellum (e.g., dysfunction of the neural integrator/gaze holding apparatus) by the CPA mass, there was left-beating ipsilesional "gaze-evoked" nystagmus in left gaze. Note the larger amplitude and lower frequency gaze-evoked nystagmus in left gaze. Because of involvement of the left 8th cranial nerve, there was right-beating contralesional "vestibular" nystagmus in right gaze (in accordance with Alexander's law). Note the smaller amplitude and higher frequency vestibular nystagmus in right gaze.
