ABSTRACT
Objective To explore the clinical and MRI features of central neurocytoma(CNC).Methods The clinical and MRI data of the pathologically confirmed CNC were retrospectively collected and compared,all the patients had undergone pre-surgery MRI plain and contrast enhanced scans.Patients were divided according to the location of the tumor as intra-lateral ventricle and ex-lateral ventricle group.Results Forty patients were finally enrolled,all tumors were solitary,39 of which were located in the ventricular system,including 2 7 cases located in lateral ventricle and 1 2 in the lateral ventricle,2 in third ventricle,5 in both lateral and third ventricle and 5 involving the whole ventricles;and 1 located in ex-ventricle(left temporal lobe).The tumors showed iso-intense on T1WI and T2WI with varying degrees of cystic degeneration.Hemorrhage was shown in 5 cases,calcification in 2 cases,markedly hyper-vascular enhancements were shown in 36 cases with 26 cases presented visible enhanced vessel sign.The comparison analysis between intra-and ex-lateral ventricle groups revealed that,the patients age,tumor size and Ki-67 expression were higher in ex-lateral ventricle group(P<0.05);hypervascular enhancement (P<0.05),gender ratio,cystic/cystic-solid appearance and vessel sigh(P>0.05)were lower than those in intra-lateral ventricle group.Conclusion CNC is typically located in lateral ventricle,with cystic and necrotic degeneration areas,hypervascular enhancement with visible vessels in solid portion on enhanced MR images;The ex-lateral ventricle CNC is rare,it commonly presents a larger tumor with high Ki-67 expression,and moderate enhancement with less visible vessels on enhanced MRI.
