MRI brain demonstrates extra-axial mass in left posterior parasagittal region. The mass displays variable signal on T1WI. Most of the mass is isointense to gray matter and its peripheral portion hyperintense. On T2WI/FLAIR the lesion is isointense to gray matter with a peripheral hypointense rim. The peripheral rim shows blooming on SWI, suggesting blood products. The lesion enhances avidly and homogeneously after IV contrast administration. No diffusion restriction. Perilesional white matter edema with compression of the posterior third of the body of corpus callosum.
Bilateral punctate-to-confluent areas of T2WI/FLAIR hyperintensity in deep white matter of fronto-parietal lobes.
