Figure 1: (a) NCCT head showing hypodense lesion in right parietooccipital region with surrounding perilesional edema. (b) MRI plain T1WI axial showing hypointense lesion and (c) ring enhancement on contrast. (d) MRI T2WI axial showing hyperintense lesion with perilesional edema. (e) MRI contrast T1WI sagittal showing ring enhancing lesion and a few satellite lesions. (f) MRI FLAIR coronal image showing almost isointense lesion with surrounding edema. (g) MRI DWI showing restriction of diffusion and (h) postoperative NCCT head showing complete excision of lesion. NCCT = Noncontrast computerized tomography, MRI = magnetic resonance imaging, T1WI = T1-weighted imaging, T2WI = T2-weighted imaging, FLAIR = fluid-attenuated inversion recovery, DWI = diffusion-weighted imaging
