A right temporo-parietal fairly defined lobulated marginally enhancing cystic mass lesion is seen, it measures about 4.3 X 3.7 X 2.6 cm in its maximal TS, AP and cranio-caudal dimensions.
The core of the lesion shows T1 hypointense and T2 hyperintense signal intensity and demonstrating evident restricted diffusion with high DWI and low ADC / high exponential ADC signals. The margin of the lesion shows hyperintense T1 and hypointense T2 signal with intense post-contrast enhancement.
The lesion is surrounded by moderate vasogenic brain edema with compression of the right lateral ventricle and contra-lateral mid-line shift as well as mild dilatation of the 3rd ventricle with slight dilatation of the left lateral ventricle and mild periventricular T2/FLAIR hyperintensity. The lesion is effacing the related cortical sulci as well.
