case_images: No involvement of the posterior spinal elements or intraspinal extension was noted (Figures 1(a) and 1(b)).
case_images: Axial CT image demonstrating a paraspinal mass composed of a mixture of fat and muscle. No bony involvement noted.

case_images: A CT scan was also performed and demonstrated a lesion composed of fat and other soft tissue (Figure 2).
case_images: Low magnification view of myolipoma. The tumour is characterised by lobules of adult-type (mature) adipose tissue intimately admixed with sheets and septa of smooth muscle. Both components lack cellular atypia (H&E stain; 2x magnification).

case_images: This was characterised by elongated spindle cells with cigar-shaped nuclei and eosinophilic cytoplasms, arranged with a fascicular growth pattern (Figure 3).
case_images: Immunohistochemistry. Picture showing immunoreactivity for desmin, a myogenic marker, in the nonfatty component.

case_images: The smooth muscle nature of the nonfatty component was demonstrated by a diffuse and strong immunoreactivity for smooth muscle actin and desmin (Figure 4).
