[Epidermoid cysts in the area of the pontocerebellar angle]

Five cases of epidermoid tumours in the vicinity of the pontocerebellar angle were treated surgically. The mean age of the patients was 31 years. Four were women, one man. Good and very good result was achieved in 80%. The surgical technique and difficulties in cases of epidermoids in this situation are described. The own experience of the authors is compared with the reports of other authors and the need for radical removal of the lesion is stressed since malignant transformation is possible, even long after operation.
