Movement disorders associated with spontaneous intracranial hypotension. This video displays mild kinetic tremor of bilateral hands without postural or resting components. The ambulatory pattern is characterized by gait start hesitation in addition to a mild ataxic component and an abnormal tandem gait (segment 1). A non-contrast brain magnetic resonance imaging (MRI) T1 sagittal slice shows minimal downward displacement of brain structures. Contrast-enhanced brain MRI shows diffuse and linear meningeal enhancement that involves the pachymeninges of both the infra- and supratentorial compartments without evidence of involvement of the leptomeninges (i.e., no abnormal enhancement around the brainstem, within the depth of the cerebral sulci or the Sylvian fissures) (segment 2).
