Cerebrospinal fluid leakage is associated with several symptoms, such as headache, nausea, photophobia, diplopia and lassitude. In our practice, dizziness is a frequent presenting symptom in patients with this disorder. However, the mechanism and features of dizziness are unclear.
In this report, we examined two patients with cerebrospinal fluid leakage with dizziness, exhibiting in particular flutter-like oscillations. Ocular flutter is characterized by intermittent bursts of horizontal saccades lacking an intersaccadic interval. Although the precise mechanisms are unknown, ocular flutter is often observed in cerebellar or brainstem lesions. In patients such as ours, ocular flutter may indicates that a central nervous system disorder may be present in cerebrospinal fluid leakage with dizziness.
