摘要
Abstract
Objective To raise the preoperative accurate diagnostic ratio of central neruocytoma by CT and MR. Methods To retrospectively analyze the manifestations of 13 central neruocytomas confirmed by surgery and pathology on CT and MR, then summarize the features.Results The tumor's location:9 cases located at diaphragma ventriculom lateralium(including 7 cases nearing to Monro hole) ,3 cases located at lateral cerebral ventricular wall,1 case located at corpus callosum. The tumor's imageology:8 cases appearanced honeycomb or fasciculus vascularis luffae changes.There were funicles between each central neurocytoma and lateral cerebral ventricular wall in 5 cases.Parenchyrna of each central neurocytoma was isodense or slightly hyperdense on CT,isointense or slightly hypointense signals on MR.and mild or midrange enhancement on enhancement scan.In 10 cases, the parenchyma of each was mild or obvious hyperintense signals on DWI, especially the mottled hyperintense signals in some cases were their characteristics.The average ADC value was(0.84±0.11) × 10-3 mm2/s.Blood vessels were found in 4 cases and strip or lamellar calcifications were found in 3 cases.Conclusion The calcifications of tumor are more clearly on CT,the honeycomb or fasciculus vascularis luffae changes of tumor are more clearly on MR.The mottled hyperintense signals of tumor parenchyma reflect the histologic characteristics in some degree.关键词
