Tumefactive demyelinating lesions or tumefactive multiple sclerosis constitute a unique presentation of demyelinating disease which frequently mimics intracranial neoplasm, infection or other, non-demyelinating intracranial pathology. Consequently, these lesions, which are larger than typical multiple sclerosis plaques and generally characterized by certain magnetic resonance imaging features including edema and incomplete ring enhancement, pose a serious diagnostic challenge that frequently prompts biopsy in initial evaluation. Biopsy can be averted when imaging features for tumefactive multiple sclerosis are seen on MRI. Herein, we present a biopsy-proven case of tumefactive multiple sclerosis with atypical imaging features, evaluated using magnetic resonance and diffusion tensor imaging.
