See-saw nystagmus (SSN) is characterized by a rotatory nystagmus, with the eyes moving conjugately clockwise and then counterclockwise. During the torsional movements,the intorting eye elevates while the opposite eye, which is extorting, falls. Acquired SSN most often occurs with parasellar or chiasmal mass lesions, but has been associated with many diseases but not with Neurosarcoidosis (NS).
30 year-old woman, presented with blurred vision, difficulty walking and intermittent diplopia for three weeks. On exam, see-saw nystagmus was noted, with intact extraocular movements. No weakness was noted. Her gait was ataxic. CT of the head revealed hydrocephalus and MRI of the brain with gadolinium showed prominent ventricular system without enhancement of meninges. CSF analysis showed hypoglicorrachia and hyperproteinorrachia as well as lymphocytic pleocytosis. CT scan of the chest showed symmetrical hilar and mediastinal lymphadenopathy and the bronchial biopsy showed granulomas. The patient was started on steroids, and later, because of no improvement in the hydrocephalus, underwent shunt placement. Three months after the procedure the patient remains asymptomatic.
There are no reports of SSN associated with NS, but it is possible that granulomas in the Interstitial Nucleus of Cajal, may have been the reason of SSN in this patient, although increased pressure in the ventricles may have played a role.
