A case of pediatric tumefactive demyelinating lesion misdiagnosed and treated as glioblastoma.

Because of their clinical and neuroradiological features, tumefactive demyelinating lesions, or giant plaques, are easily mistaken for tumors, with a consequent risk of gross errors in the choice of treatment. This article reports a 10-year-old girl who underwent surgery for a left parietal lesion misinterpreted as a glioblastoma which subsequently proved to be a case of giant plaque.
