"T1: unilateral cortical atrophy with ex vacuo ventricular dilatation 15"
"T2: hyperintense signal areas in the cortical and subcortical regions of the affected hemisphere 15"
"DWI/ADC: restricted diffusion may be seen in altered signal areas 15"
"T1 C+ (Gd): no significant post-contrast enhancement 15"
"The exact cause of the disease is unknown. However, various viral (SSPE-like, EBV or CMV) or inflammatory episodes have been implicated by different authors 3,4,6. Additionally, an autoimmune mechanism has also been proposed describing antibodies against the GluR3 subunit of the α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor in a few patients 11,17."

"Radiographic features are usually isolated to a single hemisphere, with a slight preference to the left hemisphere 18; however, bilateral Rasmussen encephalitis has also been described in numerous case reports 12-14."
"CT may not show any specific feature in early imaging; however, patchy hypodense attenuation areas (similar to viral encephalitis) may be seen. The late-stage disease may show unilateral cortical atrophy. CT perfusion may show decreased cerebral blood flow (CBF) 1."
