  • Abstract
  • Look Inside

Pathology of pinealomas has been much in dis-pute and pathogenesis of pinealomas outside the pineal gland is interesting. Pinealomas of the cere-bellopontine angle has scarcely ever been reported in litereture. We have experienced two cases of pinealomas of the cerebellopontine angle.

The first case was a 36-year-oldman, who deve-loped the left facial palsy, impairment of the left auditory acuity with tinnitus and staggering gait.

By the help of Myodil ventriculography, the tumor near the pineal area invading the left cer-ebellopontine angle was suspected, which was ascertained at the operation. The pathological diagnosis of the tumor was pinealoma. In this case, the pinealoma at the pineal gland is consi-dered to extend postero-laterally through the am-bient cistern into the cerebellopontine angle.

The second case was a 41-year-old man, who developed the right facial palsy and tingling of the right face. On the roentgenologic examination, the tumor of the cerebellopontine angle or the pineal region was not certain but at the operation the tumor in the right cerebellar hemisphere near the ventro-lateral surface was discoverd, of which the histological diagnosis was pinealoma. The tumor may have its origin at the ependymal lining of the 'velum medullare laterale'.

The report of such a case of pinealoma is not dis-covered in literatures and this case is very much interesting for this point of view.
