Pelvic CT shows a large, well-defined, presacral, inhomogeneous, multilobulated, soft tissue mass, arising from the anterior aspect of upper sacrum. It displays increased attenuation (HU range : +70 to +95). Foci of calcification are seen within the lesion. Similar but smaller lobulated mass is also seen in the anterior part of lower sacrum. Osteopenia and accentuated trabecular pattern of the sacrum, without osseous destruction, is noted in the bone window images.
