Abstract

Neurological findings in moyamoya disease (MMD) are various, mostly related to cerebrovascular events. Movement disorders such as dystonia, chorea or dyskinesia are rarely reported. Chorea gravidarum is a very rare movement disorder in MMD. In this article, we present a 26-year-old female patient whose first symptom was chorea and who was diagnosed as demyelinating disease first, while she was later diagnosed as MMD after magnetic resonance angiography and digital subtraction angiography.
