    T1-weighted SE coronal image shows a gluteal mass extending to the intrapelvic area from the piriformis muscle. The lesion has inhomogeneous signal intensity, mostly peripherally. The intrapelvic parts of the lesion...

     
    Area of Interest: unknown; Imaging Technique: Preoperative MR imaging;

    On T1-weighted SE sagittal image, the gluteal mass has bright signal areas in the upper part of the tumour and the remaining part of the tumour shows inhomogeneous hypo- and iso-intense signal changes.

     
    Area of Interest: unknown; Imaging Technique: Preoperative MR imaging;

    T1-weighted SE axial image shows anterior displacement of the bladder due to compression by the intrapelvic part of the tumour.

    T2-weighted TSE fat-supression coronal image demonstrates bright signal areas corresponding to fatty tissue on T1-weighted images of the tumour.

     
    Area of Interest: unknown; Imaging Technique: Preoperative MR imaging;

    T2-weighted axial image shows inhomogeneous signal changes and extension to the pelvic region.

    There is no recurrent tumour on T1-weighted coronal image.

     
    Area of Interest: unknown; Imaging Technique: Postoperative images;

    On T1-weighted axial image, there is no tumour reccurence at the piriformis muscle level and no displacement of the bladder.
