Extraventricular Neurocytoma with Ganglionic Differentiation Associated with Complex Partial Seizures

(‘‘cerebral’’) neurocytoma with ganglion cells located in the right temporal lobe in a 9-year-old girl with complex par-tial seizures and precocious puberty. CT showed a calcified mass with central cystic zones. MR imaging showed a markedly hyperintense predominately solid tumor on both T1- and T2-weighted images, without appreciable contrast enhancement. Cerebral neurocytomas are histologically be-nign and radical surgery is curative; they should be in-cluded in the differential diagnosis of temporal lobe tumors in children. Central neurocytoma, first described by Hassoun et al in 1982 (1), is a rare neuronal tumor of the CNS accounting for 0.25 % to 0.5 % of all CNS tumors (2). The term central underscores the fact that most neurocytomas are located within the ventricula
