Most importantly, our patient had unremarkable structural imaging for over 8 years followed by sudden appearance of marked signal changes on MRI suggesting malignancy and necessitating brain biopsy. Malignant transformation of a slow growing tumor causing progressive neurological deficits and seizures became the main suspected diagnosis after late MRI abnormalities appeared.
