case_images: Brain MRI with contrast was done and showed right parieto-occipital cortical and subcortical mass lesion measuring about 1.5 x 1.5 cm that has a low signal intensity on T1 and intermediate signal intensity on T2 and FLAIR with intense enhancement postgadolinium administration mainly peripherally with few small susceptibility artefact on T2 associated with significant vasogenic oedema and mass effect on the adjacent sulci (Figure 1).
case_images: (a) Microscopic examination of the tissue under a low power with H&E staining. Under a moderate power (b) and a high power (c) magnification, areas of nuclear palisading of bland looking spindle cells with dense cellular area alternating with loosely textured myxoid area, consistent with Antoni type A and Antoni Type, B respectively. (d) Epithelial membrane antigen protein staining was negative.
