Axial section of computed tomography scan (a) showing an intra-osseous bony neoplasm. Bone window of axial section (b) and sagittal section (c) showing classical sunburst pattern of bony tumor. Expansion and thinning of inner and outer table is obvious. Axial section of magnetic resonance imaging scan showing hypo-intense signal indicating loss of fat on T1-weighted imaging (d) and hyper-intense signal on T2-weighted imaging (e). Sagittal section of contrast-enhanced magnetic resonance imaging scan (f) showing intra-osseous tumor over torcula
