Reperti
- Heterogeneous mass in the left cerebral hemisphere measuring 5.3 x 5 x 6 cm
- Corresponding heterogeneous enhancement with matching areas of restricted diffusion
- Areas of intrinsic T1 signal hyperintensity, particularly along the deep margin of the mass
- Surrounding vasogenic edema and associated mass effect resulting in local sulcal effacement, crowding of the left lateral ventricle, and 10 mm left-to-right midline shift
- Entrapment of the temporal horn of the left lateral ventricle
