  • Abstract
  • Look Inside

A 37 year-old-male with von Recklinghausen's disease complained of left sudden deafness and tinnitus. He was treated with steroid and hearinglevel was recovered. However, fluctuation of hearing loss was occurred after the treatment.

Temporal bone tomography showed that the internal auditory canal was 2 mm larger in the left than the right. CT showed no evidence of tumor. However, MRI showed the high intensity lesion on the left internal auditory canal.

The cause of dilatation of the canal was suspected to be a dural ectasia secondary to inflammation, because there was no anatomical relationship of the high intensity lesion to the course of 8th cra-nial nerve.
