Abstract

Subependymomas are rare benign central nervous system tumor which account of 0.7% of all intracranial tumors. Subependymomas show characteristic MR findings according to their location. However, sometimes atypical findings could be found. In addition, subependymomas can occur very rarely in the spinal cord. We report two cases of pathologically confirmed subependymoma, one of which shows atypical appearances in spite of their intraventicular location and the other of which shows rare case of spinal intramedullary subependymoma. We review the clinical symptoms and radiologic findings of two cases.

상의하세포종은 드문 중추신경계 종양으로 두개내 발생하는 종양의 0.7%를 차지한다. 두개내 상의하세포종은 위치에 따라 특징적인 MR 소견을 보여주는데 가끔 비전형적인 소견도 존재할 수 있다. 또한 매우 드물게는 척수내에 발생하기도 한다. 우리는 각각 뇌실내 위치에도 불구하고 비전형적인 소견을 보인 경우와 드물게 척수 내에 나타난 상의하세포종의 경우, 두 가지 조직학적으로 확진된 상의하세포종 증례를 소개하고 그 임상적 증상과 영상학적 소견에 대해 고찰하려고 한다.
