Background The fndings of head impulse tests (HIT) are usually normal in cerebellar lesions. Case Report A 46-year-old male presented with progressive dizziness and imbalance of 3 weeks duration. Te patient exhibited catch-up saccades during bedside horizontal HIT to either side, which was more evident during the rightward HIT. However, results of bithermal caloric tests and rotatory chair test were normal. MRI revealed a lesion in the inferior cerebellum near the focculus. ConclusionszThis case provides additional evidence that damage to the focculus or its connections may impair the vestibulo-ocular refex only during high-speed stimuli, especially when the stimuli are applied to the contralesional side. By observing accompanying cerebellar signs, the abnormal HIT fndings caused by a cerebellar disorder can be distinguished from those produced by peripheral vestibular disorders.

Epidural blood patch (EBP) is one of the treatments for spontaneous intracranial hypotension (SIH), and its complicationshave rarely been reported. We report a patient with SIH and developed intracranial hypertension after EBP. Themechanism of rebound intracranial hypertension was uncertain. If the patient presented with a different type ofheadache or newly developed neurological symptoms after treatment of SIH, rebound intracranial hypertension shouldbe considered and the proper treatment needed quickly.
