Fig.: - RING MENISCUS Three consecutive coronal T2-W fat-suppressed images of a 40-year-old man, identifying a triangular shape meniscal tissue (thin white arrow) on the central portion of the lateral compartment, compatible with a ring meniscus. 环状半月板:男,40岁,冠状位抑脂T2WI序列连续三层图显示内侧髁间隙的三角形半月板组织(细白色箭头)。 原文:https:///articles/ring-meniscus A ring meniscus is a very rare anatomical variant of the lateral meniscus of the knee. The inner margin of a ring meniscus on coronal images can easily be mistaken for a bucket-handle meniscal tear displaced into the intercondylar space, so it's usually diagnosed during arthroscopy. 环状半月板是膝关节外侧半月板的罕见的变异。 环形半月板的内侧缘在冠状图像上容易被误认为是半月板桶柄状撕裂后移位到内侧髁间隙,通常在关节镜检查时发现。 |
