Magnetic resonance imaging diagnosis of central neurocytoma

Objective To evaluate the characteristic appearance and diagnosis value of central neurocytoma on magnetic resonance imaging (MRI).Methods MRI data of 9 patients with central neurocytoma confirmed surgically and pathologically were retrospectively reviewed.Results All the lesions located in the lateral ventricle septum pellucidum,adjacent to Monro hole,in the anterior 1/3 to 2/3 of the lateral ventricle.Most of them were irregularity,sublobe and sharpness of border.They presented as inhomogeneous intense signal on MRI,with slight to equal enhancement on enhancement.DWI could be high or slightly high signal.Conclusion Central neurocytoma has the characteristic appearances on MRI,being helpful to the diagnosis.
