Epidermoid cysts in both occipital bone and cerebellum with intact dura mater: a case report

Abstract

A 71 year-old male was diagnosed of epidermoid cyst located in diploe and cerebellum. The skull part was found firstly and kept steady for more than 5 years. The cerebellar part was found nearby when dizziness and vomit happened. The patient has gone through a traumatic brain injury 4 decades ago. All lesions were resected totally. Interestingly the dura mater was confirmed intact without any leakage into subdural space. Imaging and pathological materials are collected completely. Conclusion: We report a case that EC was found in both skull and cerebellum whereas the dural mater was intact. Epidermoid cell migration or infiltration are possible explanations. Gross total resection is advanced for better clinical outcome.
