Abstract

To accurately interpret knee MRI, it is important not only to know the basic meniscal anatomy but also to distinguish it from that under pathological conditions. Thus, it would be helpful to know the normal meniscus variants (false positives) that could be mistaken for meniscal tears, and tears that could easily be missed and incorrectly diagnosed as normal (false negatives). False positives include synovial recesses, meniscal flounce, the relationship between the popliteus tendon and lateral meniscus, transverse ligament, the anterior root of the meniscus, and meniscofemoral ligament. False negatives include focal radial tears, flap tears, posterior root tears, meniscocapsular separation, and discoid meniscal tears. In this pictorial essay, we reviewed the imaging data obtained in the aforementioned cases.

무릎 MRI를 정확하게 판독하려면 기본적인 반월연골 해부학을 아는 것뿐만 아니라 병적 상태와 구별하는 것이 중요하다. 따라서 반월연골 열상으로 쉽게 오인될 수 있는 정상 변이(위양성)와 쉽게 놓쳐서 자칫 정상으로 오인될 수 있는 반월연골열상들(위음성)을 아는 것이 판독에 도움이 될 것이다. 위양성에는 활막 오목, 반월연골 주름, 슬와 힘줄과 외측 반월연골 사이의 관계, 가로 인대, 반월연골 앞 근 및 반월대퇴 인대가 포함된다. 위음성에는 국소 방사열상, 피판 열상, 뒤 근 열상, 반월연골-관절낭 분리, 원반모양반월연골의 열상이 있다. 이번 임상화보에서는 앞서 언급한 상황들로부터 얻은 영상자료들을 검토해보았다.
