Figure 12

48-years female smoker with lung cancer developing lumbar and right limb pain. MRN images in axial T1 (a), axial T2 fat suppression (b), axial T1 VIBE post contrast (c) and coronal STIR 3D SPACE MIP (d) show a large right hip mass (solid arrow) with soft tissue components and necrosis associated with edema and enhancement of adjacent soft tissues (arrowhead). The inflammatory process involves the sciatic nerve (wavy arrow), with thickening and contrast enhancement. Femoral neuropathy is also seen (star).
