Abstract

Objective:To evaluate the characteristic appearance and diagnotic value of central neurocytoma on MRI.Methods:MR imagings of 8 patients with central neurocytoma(CNC) confirmed surgically and pathologically were retrospectively reviewed.Results:5 cases of CNC were located in the anterior 2/3 0f the lateral ventricle,2 case of CNC was located in the posterior 2/3 0f the lateral ventricle,and 1 case was located in the foramen of monro.Most of them were irregularity,sublobe and sharpness of border.MRI T1WI and DWI could be equal,slightly low or slightly high signal. T2WI could be equal or slightly higher signal.They showed inhomogeneous enhancement after intensified scanning,but,cyst lesions,calcifications and bleeding had no enhancement.Conclusion:The MR imagings of CNC have the better characteristic appearance.The pathological basis contributes to the diagnosis of the CNC.
