A 21-year-old male with a surgically confirmed normal medial meniscus, which was interpreted as a meniscal tear by all readers using 3D SPACE and as a normal meniscus by all readers using the routine MR protocol. Sagittal (a) and coronal (b) 3D SPACE images demonstrate grade 3 signal in the posterior horn of the medial meniscus extending to the inferior surface (arrow). Coronal 2D TSE intermediate-weighted FS (c) and T1-weighted (d) images show normal medial meniscus. Poor image contrast on 3D SPACE images was considered the primary cause of the discrepancy
