Recurrent meningitis due to epidermoid

Abstract

Aseptic meningitis is characterized by noninfective serous inflammation of the meninges. It can occur in a recurrent fashion when associated with dermoid and epidermoid cysts due to rupture of cyst contents into subarachnoid space resulting in aseptic chemical meningitis. Bacterial meningitis in association with these tumors is commonly related to a coexisting dermal sinus tract and the most common organism is Staphylococcus aureus.
