  • Figure 1
    MR of the right knee
     

    T1-WI axial: a mass well-defined, ovoid, and predominantly intermediate is shown, dorsal to the posterior cruciate ligament (see arrow).

     
    Area of Interest: Musculoskeletal joint; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Pathology;

    STIR sagittal image: the mass is predominantly intermediate, the close relation with the posterior cruciate ligament is nicely demonstrated (see arrow).

     
    Area of Interest: Musculoskeletal joint; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Pathology;

    T2-WI fat-saturated gradient echo sagittal image: demonstrates multiple and small markedly hypointense areas within the mass (blooming artifact - see *).

     
    Area of Interest: Musculoskeletal joint; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Pathology;

    T1-WI axial image after gadolinium: demonstrates intratumoral intense and homogeneous enhancement (see arrow).
