Figure 2: MRI Brain after 3-months shows a well-defined conglomerate ring lesion in left posterior frontal region. The peripheral rim is hyperintense on T1-WI (a), hypointense on T2-WI (b). The core of the lesion is hypointense on T1-WI (a) and hyperintense on T2-WI (b and e). The core of the lesions is bright in diffusion trace image (c) and dark in ADC image (d) suggesting diffusion restriction. Large single focus of calcifications was present on susceptibility weighted image (f). On post contrast images (g and h), peripheral multi-lobulated smooth rim enhancement was noted without any enhancement in core of the lesion
