PDFAbstract
Obsjective To investigate the imaging characters on MR and pathological feature of central neurocytoma. Methods Imaging findings and pathological features of 12 patients with histopathological diagnosis of CNC were evaluated retrospectively. Results 9 cases were located in the lateral ventricle close to Monro Foramina, one was in the mesencephalon and two in the thalamus.The mass could appear various mixed singnals on T1WI and T2WI with well-defined edge. Cystolization, hemorrhage, calcification and "cords sign"could be seen. After contrast administration, the solid parts of the mass were significant enhanced. CNC were composed of uniform small round cell sheet arranged and characterized by pseudorosette and nucleus-free area formed of dense flbrillar matrix. Syn and NeuN were overexpressed in CNC. Conclusion CNC that located in lateral ventricle with "cords sign" and Cyst in young adults could be easy diagnosed. But extraventricular CNC that lacked identifiable imaging characters could be diagnosed with the help of immunohistochemical analysis of Syn and NeuN.
