Axial brain-parenchyma (a) and bone windows (b) of brain in non-enhanced CT demonstrating a parietal mass with subtle hyperostosis and internal calcifications. Axial T2 WI (c,d) shows a lobulated mass which is predominantly hyperintense but with some foci of low signal. Significant mass effect and subtle edema is noted. T1-WI postcontrast (e) and axial T2* MRI perfusion (f) images show a heterogeneous enhancement with honeycomb pattern and low CBV of the tumor
