The value of "streaks" sign in diagnosis of central neurocytoma

Abstract

Objective To investigate the value of “streaks” sign in diagnosis of central neurocytoma.Methods Fifty-two cases of central neurocytoma confirmed by pathology from 2008 to 2011 were collected.In 52 cases,both MRI and CT scan were performed on 12 patients,MRI only on 36 patients and CT only on 4 patients.MRI and CT features were analyzed retrospectively.Results In MRI,the “streaks” sign was found in 39 cases,accounting for 81.25％(39/48).In CT,the “streaks” sign was found in 11 patients,accounting for 68.75％(11/16).The “streaks” sign in CTwas also found in MRI.Conclusions There is a certain specificity of “streaks” sign in central neurocytoma imaging.In combination with other imaging findings,it can be helpful for an accurate preoperative diagnosis of the disease.
