Abstract:
20, or the grade of difference is 1 or above), while no difference of bilateral enhancement was found in 1 case. Abnormal enhancement of ganglion geniculi (4/4) and labyrinthine segment (3/4) was relatively frequent, abnormal enhancement of distal part of internal auditory segment, tympanic segment, and mastoid segment was seen in 2 cases, respectively.Conclusion MRI doesn't have diagnostic value unless the enhancement of segments of the affected facial nerve side is more evident than the unaffected side for unilateral cases. Labyrinthine segment and ganglion geniculi are more susceptible to Ramsay Hunt syndrome. Gd-DTPA enhanced MRI can demonstrate segmental lesions of facial nerves objectively, thus it can be helpful in the diagnosis and differential diagnosis of Ramsay Hunt syndrome. The relationship between MRI findings and clinical representation still needs further study.
