Abstract

Extraventricular neurocytoma (EVN) is a rare neuroepithelial tumor. Its propensity to occur in cerebral hemisphere is much higher. EVN has a histological resemblance to central neurocytoma but radiologically, it is more complex. Ganglionic differentiation is more common in EVN and tends to have more of a cystic component. Calcification is frequent but hemorrhage is only an occasional finding. Although it has been reported to occur in various regions, the propensity to occur in cerebral hemisphere is much higher. Herein, we report two cases which presented as a mass in the right frontal lobe and right parietal lobe. MRI showed hypointesity on T1, hyperintesity on T2-weighted images with moderate enhancement after contast injection. In short extraventricular neurocytoma should be considered indifferential diagnosis of complex intracranial masses.
