    T1- and T2-weighted MR images
     

    Sagittal T1-weighted MR image reveals an isointense tumour in the sacral region, extending from the skin, subcutaneous connective tissue and gluteal musculature to sacral bone and dorsal wall of the rectum.

     

    Sagittal T2-weighted MR image reveals a heterogeneous hyperintense tumour in the sacral region, extending from the skin, subcutaneous connective tissue and gluteal musculature to sacral bone and dorsal wall of the...

     

    Axial T1-weighted MR image reveals an isointense tumour involving sacral bone from S2 segment.

    Postcontrast T1-weighted MR images
     

    Post-contrast sagittal T1-weighted MR image demonstrates heterogeneous enhancement of tumour. There is also enhancement in areas of active infection, surrounding unenhancing foci of pus.

     

    Post-contrast axial T1-weighted MR image reveals heterogeneous enhancement of tumour involving sacral bone from S2 segment, gluteal musculature, and subcutaneous connective tissue.

     

    Post-contrast axial T1-weighted MR image demonstrates that dorsal wall of the rectum is involved.
