Patient
female, 44 year(s)
 
 
  • Figure 1
    Axial PD MRI
     

    Distal third thigh level: the semitendinosus tendon (yellow arrow) is slightly thickened and inhomogeneous. A small fluid collection surrounds the tendon.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Femoral condyles level: more evidence of inhomogeneity of the semitendinosus tendon(yellow arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Articular level: split of the semitendinosus tendon (yellow arrow); gracilis tendon (curved arrow) and sartorius muscle (asterisks)are normal.

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Tibial plateau level (semitendinosus tendon - yellow arrow; sartorius muscle - asterisks; gracilis tendon - curved arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 2
    Axial T2w FS MRI of the knee

    Fluid collection surrounding the ruptured semitendinosus tendon (yellow arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 3
    Sagittal MRI of the knee
     

    PD MRI: rupture of the semitendinosus tendon (yellow arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;

    T2w FS MRI: strain of semimembranosus myotendinous junction (white arrow); stump of the semitendinosus tendon (yellow arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;
     
     
  • Figure 4
    Coronal T2w FS MRI
     

    Retraction of the ruptured semitendinosus tendon (yellow arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Distal tendon stump (yellow arrow).

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