A frontal tumefactive demyelinating lesion mimicking glioblastoma differentiated by methionine positron emission tomography

Tumefactive demyelinating lesion (TDL) is often reported as a rare variation of multiple sclerosis (MS). TDL is difficult to diagnose solely by magnetic resonance imaging (MRI) in patients with no history of MS. This is because the lesion often shows ring enhancement with perifocal brain edema on gadolinium MRI, thus mimicking glioblastoma multiforme (GBM).
