PDFAbstract
Objective To investigate the imaging features of neuronal and mixed neuronalglial tumor. Methods The imaging findings and clinical history of 33 subjects with the neuronal and mixed neuronal-glial tumor proven by surgical pathology were analyzed retrospective1y. Results 5 cases of central neurocytomas, 4 cases were located in the lateral ventricle with cystic changes and mild to moderate enhancement. 5 cases of dysembryoplasia neuroepithelial tumor, mainly seen in the supratentorial brain and beneath cerebral cortex, appearing as low signal intensity on T1WI and high signal intensity on T2WI, DNT had a well-demarcated and no or only slight edema，no enhancement; 20 cases of gangliogliomas, mainly seen in the temporal lobe, with partly or mainly cystic mixed signals after contrast enhancement, 2 cases could be seen calcification. 3 cases of desmoplastic infantile astrocytoma/ganglion glioma, also showed cystic solid mixed signals, only slight edema, wall and solid part of the tumors were obviously enhancement. Conclusion Neuronal and mixed neuronal-glial tumor have some imaging characteristics and thus provide accurate preoperative diagnosis with closely combining the clinical history.
