Abstract：Objective To investigate the MRI features of the central neurocytoma and to improve preoperative diagnosis. Methods MR imagings of 11 patients with central neurocytoma confirmed surgically and pathologically were retrospectively re-viewed and compared with pathological analysis. Results 7 cases located in the anterior 2/3 of the right of lateral ventricle, 2 cases located in the posterior 2/3 of the lateral ventricle, 1 case located the left of lateral ventricle and 2 cases located in the fora-men of monro. Most tumors presented as isointensity or slight hypointensity signal on T1 WI and isointensity or slight hyperintensity signal on T2 WI. MRI manifestations within the solid tumor included"honeycomb"or"vegetablesponge"and flow void effect (72. 7%, 8/11), scalloping appearance (81. 8%, 9/11). 2 cases presented with bleeding, 1 case with cavernous hemangioma. On enhanced MRI, 9 cases of the lessions had slight enhancement, 1 case had marked inhomogeneous enhancement and 1 case had no enhancement. Immunohistochemistry examination was employed in 11 cases. Syn and NSE were positive. Conclusion The MR imagings of CNC have the better characteristic appearance, and to deepen understanding can improve the diagnostic accu-racy.
