Abstract:
Objective To evaluate the MRI features of central neurocytoma (CNC). Methods Thirteen patients with CNC (7 males and 6 females, aged 18-28), admitted to our hospital fiom January 2007 to January 2010, were chosen; preoperative plain and contrast enhanced MRI scans were performed on these 13 patients and 1 also received CT scan. The clinical and imaging data and pathological features of these patients were retrospectively analyzed. Results The largest tumor enjoyed its maximum diameter of 3.2-8.5 cm; the CNC in 12 patients located at the lateral ventricle and that in 1 patient at the parenchyma of the left frontal and temporal lobes. Lobulated solid tumors were noted in these lesions,showing T1 isointense and T2 hyperintense in MRI; some multiple, scattered cystic lesions showed stronger T1 and T2 signal than the former ones; vascular "flow void" signal was shown in 6 patients in T2WI, and slightly weak T1 signal was shown in 8. All the tumors demonstrated inhomogeneous enhancement and the tumor vessels in 6 patients were noted under contrast MRI. Focal calcification was found. Conclusion CNC in the lateral ventricle enjoys typical location; considering the age of patients, non-contrast and contrast MRI findings, correct diagnosis of CNC can be made; however, CNC outside the lateral ventricle is hard to diagnose.
