AbstractEpidermoid cysts are tumours, which contain keratin, cellular debris and cholesterol, and lined with stratified squamous epithelium. Clinically, epidermoid cysts behave like benign, slow-growing lesions. We present a 63 year-old man with a 6-month history of right periorbital pain and hypaesthesia in the area of the first and second branch of the trigeminal nerve. MRI revealed an epidermoid cyst of the cerebellopontine angle extending into the middle and anterior cranial fossae. Radical surgical removal of epidermoid cysts should be attempted, but a less aggressive surgical strategy should be considered if there is strong adherence to the surrounding brain tissue, particularly in eloquent areas. In this case, complete tumour removal was achieved via a suboccipital retrosigmoid approach.
