Abstract

Intracranial dermoid cyst is a rare congenital disease originating in the embryo. Intracranial dermoid cysts are usually detected before five years of age; however, asymptomatic cysts have been discovered after the third decade of life through various complications. Sometimes, there are neurologic symptoms caused by a cystic mass effect and if there is a dermoid sinus, purulent infections can occur. Early diagnosis is important and as such, CT or MR imaging for recognition of the location, size, and characteristics of the cysts are recommended before surgical resection. Extradural dermoid cysts with an intact occipital dermoid sinus are a rare event. We report a case of intracranial dermoid cyst associated with scalp abscess. In this case, a three-year-old boy was presented with scalp abscess and we performed MR imaging, which revealed a cystic region. The prognosis after resection operation was good without any complication.
