The CT findings of a proven presacral myelolipoma are described, illustrated, and discussed. This lesion presents as an encapsulated mixed but predominantly fatty soft tissue mass located in the extraperitoneal retrorectal space. It occurs in asymptomatic individuals usually between the 5th to 8th decades, with a slight female predominance and without significant hematologic disturbances. This entity should be included in the differential diagnosis of a fat-containing presacral lesion. Familiarization with its typical CT appearance may permit a percutaneous needle biopsy diagnosis, avoiding unnecessary surgery.
A femoral Ewing's sarcoma from a 13 1/2-year-old girl with otherwise typical clinical and pathological features showed epithelial differentiation by electron microscopy and immunocytochemistry. The expression of keratin and the presence of tonofilaments in cells of this Ewing's sarcoma may enforce the hypothesis that Ewing's sarcoma derives from a multipotential primitive stem cell.
