Infected Dermoid Cyst of the Posterior Fossa: Case Report

Abstract

Intracranial dermoid cysts are a rare congenital benign neoplasms, they account for only 0.1%-0.7% of all intracranial tumors [1]. They arise from inclusion of ectodermal elements within the neural tube during its closing between the third and fifth week of embryonic development [2]. Patients with a posterior fossa dermoid cyst and an associated dermal sinus may develop bacterial meningitis or abscess formation of the dermoid itself [3]. Here in, we present a case of dermoid cyst with occipital dermal sinus, complicated by abcess.
