Co-existence of meningioma and epidermoid cyst in the posterior cranial Fossa

We present a clinical case of combined tentorial meningioma and cerebellopontine angle epidermoid cyst (EC) in a 33-year-old woman.

Description
Summary:We present a clinical case of combined tentorial meningioma and cerebellopontine angle epidermoid cyst (EC) in a 33-year-old woman. According to the literature, ours is the fifth case involving a combination of such tumours and the first in which the tumours were located in the posterior cranial fossa. Occurrence of a combination of brain tumours with different histological structures in the same patient is very rare. Nevertheless, the possibility of such a combination should always be considered, and thorough preoperative diagnostics are required to prevent complications and misdiagnosis. Currently, the combination of meningioma and EC is considered coincidental. However, the proximity of the tumours described in the available reports does not exclude the possibility of one tumour’s local influence on the other, which should be further studied.
