    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Staging; Special Focus: Neoplasia;

    Sagittal T2-weighted images showed a large, well-demarcated ovoid pelvic mass (*), with predominant low signal intensity, which displaced ventrally and compressed the urinary bladder (a) and uterus (arrowheads in b).

    Coronal (c) and axial (d..f in caudocranial order) showed a large demarcated ovoid pelvic mass (*), mostly T2-hypointense, which displaced laterally and compressed the rectum (+). Note displaced bladder and uterus...

    Pelvic MRI - Unenhanced and gadolinium-enhanced T1-weighted multiplanar images
     

    The pelvic mass showed low-to-intermediate signal intensity on unenhanced T1-weighted images. Note displaced and compressed urinary bladder, uterus (arrowhead), and rectum (+).

     
    Area of Interest: Pelvis; Imaging Technique: MR; Procedure: Staging; Special Focus: Neoplasia;

    Sagittal (b) and axial fat-saturated (c,d) T1-weighted images after intravenous gadolinium contrast show marked, inhomogeneous enhancement of the presacral pelvic mass (*) without signs of necrosis.
