Abstract

Intracranial chordoma is a rare tumor, originating from embryonic remnants of the primitive notochord. It typically appears as an enhancing extradural midline tumor with bone involvement. We introduce a rare case of a 27-year-old male who had a nonenhancing intradural chordoma showing paramedian location, involving the left cavernous sinus, Meckel's cave, and prepontine cistern. The pathologic diagnosis was confirmed as an intradural chordoma. The imaging findings of this unusual case of a nonenhancing intradural paramedian chordoma will be presented with the differential diagnosis focused on the epidermoid cyst.

두개 내 척삭종은 원시 척삭에서 기원하는 드문 종양이다. 이는 주로 조영증강하는 경막 외 정중선 종양으로 발현하며 인접한 뼈 구조를 침범하는 형태로 발현한다. 본 증례에서는 정중선이 아닌 좌측 해면정맥동, 메켈 공간, 그리고 전교뇌수조에 위치하는 드문 형태로 비조영증강 경막 내 척삭종이 발현하였다. 수술 후 병리학적 최종 진단에서는 경막 내 척삭종으로 확인되었다. 따라서, 본 증례 보고를 통해 비전형적인 양상의 비조영증강 방정중위치의 경막 내 척삭종의 영상 소견을 소개하고 표피양낭종과의 감별진단에 초점을 두고자 한다.
