There is a heterogenous mass lesion involving the right parietal cerebral cortex and white matter associated with extensive perilesional vasogenic oedema with mass effect. There is also a 12.5 mm right to left subfalcine herniation as well as right uncal herniation.
The mass demonstrates mixed low and intermediate T1. The mass also demonstrates mixed intermediate and high T2 signal intensities and peripheral contrast enhancement. The mass measures 53.5 mm x 38.7mm x 29.8 (AP x CC x Transverse). There is partial effacement of the posterior body and atrium of the right lateral ventricle as well as dilatation of the left lateral ventricle and temporal horn of the right lateral ventricle.
Impression: Right parietal cerebral heterogeneous mass with central necrosis.
