Neurocytomas are relatively rare central nervous system tumors first described in intraventricular sites but increasingly recognized in the brain and spinal cord parenchyma. Herewith, we report a case of a 3-year-old girl with generalized seizures. Computed tomography and magnetic resonance imaging revealed a lesion in the left frontal lobe. ⋯ Histopathologic examination demonstrated an extraventricular neurocytoma. On follow-up magnetic resonance imaging after 1 year, no evidence of tumor recurrence was noted. Cerebral neurocytomas are histologically low-grade tumors and radical surgery is curative; they should be included in the differential diagnosis of cerebral tumors in children.

Tumefactive demyelinating lesions are a known but uncommon complication of multiple sclerosis, a disease rarely reported in children. This is the case of a 16-year-old African American patient with multiple sclerosis, who developed 2 tumefactive demyelinating lesions. Review of the literature and our own experience helped formulate an algorithm for therapeutic options during an acute attack.
