Abstract

Schwannoma is a rare intramedullary tumor. There has been no reported case about interval aggravation on follow-up MR imaging. We report initial and follow-up MR findings of a thoracic intramedullary schwannoma with syringomyelia and edema in a patient without neurofibromatosis. Intramedullary schwannoma should be included for differential diagnosis of intramedullary tumor even though followup MR imaging shows interval increase in size of the tumor and extent of associated edema to mimic malignancy.

척수내 신경집종은 드문 척수내 종양으로 추적 자기공명영상 소견에서 악화된 증례는 보고된 바가 없다. 우리는 신경섬유종이 없는 환자에서 생긴 흉추 척수내 신경집종의 초기 영상소견과 추적 자기공명영상을 보고하고자 한다. 추적 자기공명영상에서 척수내 종양의 크기가 커지고, 동반된 부종의 범위가 증가하여 악성처럼 보여도, 척수내 종양의 감별진단에 척수내 신경집종을 반드시 포함하여야 하겠다.
