RESUMO
Bilateral facial nerve palsy or facial diplegia is a rare condition that occurs mainly in the context of Guillain-Barré syndrome. Its natural history has never been studied. We report four patients with isolated idiopathic bilateral facial nerve palsy with meningitis, no evidence of Guillain-Barré syndrome and rapid and complete recovery. Our report aims to draw attention to an unusual variant of bilateral facial palsy.

In a case of neurosarcoidosis with bilateral facial nerve palsy and hydrocephalus, contrast-enhanced magnetic resonance imaging (MRI) study and angiotensin converting enzyme (ACE) activities in cerebrospinal fluid (CSF) were valuable for the diagnosis and the follow up. Facial nerve lesions were demonstrated on gadolinium-DTPA enhanced MRI. The disappearance of enhancement was concomitant with the amelioration of facial nerve palsy after corticosteroid therapy.
