Radiographic Studies
MRI following an infusion of gadolinium showed cystic areas in the right and left temporal lobes consistent with radiation necrosis. There is minimal progression in the necrotic changes since the MRI in January 1996. There is no mass effect and no other definite focal lesions in the rest of the brain. The is no evidence of recurrence of the nasopharyngeal cancer. Goldman visual field was unremarkable.
