Axial T2-weighted image (a) shows hyperintensity involving subcortical white matter in left polar temporal region right adjacent to clival structures. Axial post-contrast T1-weighted image (b) reveals a focal non-enhancing portion related to necrotic tissue with a peripheral rim enhancement, as in grade 2 injury of LENT-SOMA scoring system
