MPNST in a 65-year-old female. Plain CT scan (A1) shows a slightly hyper-attenuated lesion in the left cheek with slight zygomatic arch erosion. On MR scan, the tumor demonstrates hypo-intensity on axial T1-weighted (A2) and heterogeneous hyper-intensity on axial T2-weighted (A3) images. Gadolinium-enhanced T1-weighted images (A4) reveal peripheral enhancement. Note the central hyper-attenuated foci on plain CT and mixed-intense signal on T2WI, which is likely to be hemorrhage. Hemorrhagic cyst was conformed in surgery
