female, 53 year(s)
 
 
  • Figure 1
    Axial T1-sequence

    On the axial T1-sequence the tumour presents as a well-defined hypointense mass in the ischiorectal fossa with significant mass effect to the closely attached pelvic diaphragm.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Screening; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial contrast-enhanced T1-sequence

    The tumour in the ischiorectal fossa shows significant enhancement. Due to the close relationship of the various anatomical compartments and the associated mass, the exact delineation of the pelvic diaphragm is obscured.

  • Figure 3
    Coronal contrast-enhanced T1-sequence

    The tumour in the ischiorectal fossa shows significant enhancement. Due to the close relationship of the various anatomical compartments and the associated mass, the exact delineation of the pelvic diaphragm is obscured.

    Coronar T2-sequence with fat suppression

    The mass presents with bright signal and a linear hypointense structure in between. Due to the close relationship of the various anatomical compartments and the mass, the exact delineation of the pelvic diaphragm is...
