  • Abstract
  • Look Inside

Intracranial lipomas are rare. Cerebellopontine angle lipomas are extremely rare. We report a case of right cerebellopontine angle lipoma. A 47-year-old woman has been suffering from right trigeminal neuralgia for about 1 year.Neurological examina-tion showed right 5th and 8th cranial nerve dysfunc-tion. MRI demonstrated the high intensity mass lesion at right cerebellopontine angle. The lesion was demonstrated as negative intensity in an opposed image by using Dixon's technique. CT showed the lesion as a very low density area (-104 Hounsfield units). Subtotal removal of the tumor was performed following right suboccipital craniectomy. Pathological diagnosis was lipoma.

We review the literature on this rare tumor and discuss the clinical symptoms, radiological findings and management.We suggest that the operation should be prudently performed for the case with only hearing disturbance because there is a high possibility that hearing disturbance will worsen.
