Facial Nerve Enhancement on Gadolinium-DTPA in a Case with Neurosarcoidosis

In a case of neurosarcoidosis with bilateral facial nerve palsy and hydrocephalus, contrastenhanced 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.(Internal Medicine 36: 825-828, 1997)
