Levodopa-responsive hemiparkinsonism secondary to cystic expansion from a coiled cerebral aneurysm

J Neuroimaging. 2015 Mar-Apr;25(2):316-318. doi: 10.1111/jon.12117. Epub 2014 Apr 7.

Abstract

An 80-year-old woman with longstanding hemifacial spasm had a 1 cm × 1.5 cm internal carotid artery terminus aneurysm treated with endovascularly delivered bare metal coils. Follow-up imaging revealed an expansile perianeurysmal cyst that coincided with development of contralateral dopa-responsive hemiparkinsonism. This is the first report of perianeurysmal cyst expansion causing levodopa-responsive hemiparkinsonism.

Keywords: Levodopa; aneurysm; cyst; hemifacial spasm; parkinsonism.
