Abstract

Objective: Analyze and explore CT and MRI characteristics of central neurocytoma(CNC), in order to improve the knowledge of this disease. Methods: Retrospectively analyze 14 cases of CNC which proved by pathology, with 8 males, 6 females, age between 21 and 65 years. The mean age was (30.3±12.0) years. Fourteen patients were all underwent conventional MRI examination, 5 patients were also underwent CT examination. Results: Ten cases located in lateral ventricles and closed to Monro area, 4 cases located in CSF disseminated sites. The mean diameter of the tumor was (5.79±1.79) cm. On CT, CNC were appeared as mixed density. Two cases were appeared as completely solid, 3 cases were seen as calcification and cysts. On MRI, CNC was isointense or hypointense to brain on T1WI, heterogeneous hyperintense on T2WI; 12 cases had a “soap-bubble” multicystic appearance and the vascular flow voids on T2WI; 8 cases had the spicules connected to the solid part of tumor and wavy ventricle wall. Contrast enhanced MRI showed heterogeneous enhancement. Conclusion: CNC has some characteristics on CT and MR images, which can help radiologist to make the correct diagnosis.
