초록
두개내 유피낭종은 발생학적으로 생기는 선천성 질환으로 대부분이 5세 이전에 진단되지만 증상이 없기 때문에 30대 이후에야 합병증으로 인해 발견되기도 하는 드문 질환이다. 유피낭종의 위치와 크기에 따른 신경학적 증상이 나타나기도 하지만 피부와의 연결관이 있는 경우에는 세균성 감염이 일어날 수 있다. 조기 진단이 중요하며 CT나 MRI를 시행하여 낭종의 위치와 크기, 성상을 파악한 후 절제술을 시행하는 것이 바람직하다. 연결관이 있는 두개내 유피낭종은 매우 드문 경우로 저자들은 두피 농양과 동반된 유피낭종이 진단된 3세 남아를 관찰하여 문헌 고찰과 함께 보고하는 바이다. 이 환아는 두피 농양이 발생하여 검사 중 선천 질환이 발견된 경우로 수술을 받은 뒤 예후는 양호하였다.
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.
