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.
