Abstract

Background:: Freezing of gait (FOG) is defined as an episodic inability to generate effective stepping in the absence of any known cause other than parkinsonism or high-level gait disorders. Methods:: We present a 59-year-old male with acute, progressive episodes of FOG. Imaging studies revealed a dural arteriovenous fistula (DAVF) associated with edema of the globus pallidus interna (GPi). Cerebral angiography confirmed the diagnosis of DAVF and demonstrated an occluded straight sinus and a retrograde blood flow of deep cerebral veins. Results:: After endovascular closure of the DAVF, a major improvement of FOG was observed concomitant with striking near resolution of GPi congestion. Conclusions:: This reversal of the clinical course, correlated with changes in imaging studies, suggests a major role of the GPi in the pathology of FOG.
