a MRI before biopsy. T1-wighted image (T1WI) shows multiple cystic lesions in the left temporal lobe causing a left to right midline shift. These cysts are displayed as high signals in T2-weighted image (T2WI) and low signals in diffusion weighted image (DWI). T2WI also demonstrate edematous brain tissue around the cysts, some parts of which shows high signals in DWI. The cyst walls and surrounding tissue are definitely enhanced by gadolinium dimeglumine (lower line). White arrows indicate the enhanced portion from which the biopsy was taken. b Pathological findings on biopsy. Hematoxylin and eosin (HE) stained section showing high cellularity and dysplasia with endothelial proliferation in the lesion (a). Giant cells and pseudo-rosettes are also identifiable (b black arrow), and areas of necrosis sections are present (c). The highest Ki-67 index is 20 % (d)
