Abstract
Nine patients with "idiopathic" hemifacial spasm were evaluated with cranial magnetic resonance imaging and angiography. Alterations of the posterior fossa vasculature, possibly related to the facial nerve irritation, were found in 8 patients (88%). Magnetic resonance angiography is a noninvasive procedure and appears to be a sensitive method to evaluate the hemifacial spasm etiology.
摘要
对9例“特发性”半面痉挛患者进行了头颅磁共振成像和血管造影评估。8例患者（88%）发现后颅窝血管改变，可能与面神经受刺激有关。磁共振血管造影是一种非侵入性检查方法，似乎是评估半面痉挛病因的一种敏感方法。
