Computerised tomography scan of the cervical spine revealed a large osseo-destructive lesion involving body of C5and C6 vertebra which was causing spinal canal compromise [Figure 1a and b].
(a) T1-weighted1 saggital magnetic resonance imaging (MRI) showing isointense mass involving anterior and posterior elements of C6 vertebral with thecal sac compression. (b) T2-weighted sagittal MRI showing isointense mass with slight hyperintensity involving anterior and posterior element of C6 vertebral body. (c and d) T1-weighted axial cuts of MRI with contrast showing mass involving anterior and posterior element of C6 vertebra with minimal contrast enhancement

It was causing distrucation of C5 and C6 vertebra body with compression of thecal sac [Figure 2a-d].
H and E, stained section shows (a) spindle cells disposed in intersecting fascicles intermingled with mononuclear foam cells. Interspersed areas (arrow) show degenerated bony trabeculae and cartilage (x200). (b) Foam cells (x400) displaying round nuclei with dense chromatin inconspicuous nucleoli and pale eosinophilic finely vacoulated cytoplasm (b)
