25 years, Female, history of cranial radiation, baseline exam. History of leukemia. There are multiple foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter which are nonspecific but compatible with posttreatment change. No intracranial mass or mass effect. No evidence of infarct or hemorrhage. Ventricles are within limits. No extra-axial collections. No abnormal parenchymal or meningeal enhancement. There is heterogeneous low T1 marrow signal including the clivus and visualized upper cervical spine which are nonspecific but compatible with history of leukemia. There is near complete opacification of the left sphenoid sinus extending into the left posterior ethmoid sinus. Paranasal sinuses are otherwise clear. Remainder of the visualized extracranial soft tissues are unremarkable.
Several T2/FLAIR hyperintense foci scattered in the periventricular and subcortical white matter which while nonspecific are compatible with posttreatment change. No intracranial mass or abnormal enhancement to suggest neoplasm.
