Abstract
Objective:To analyze the CT and MR characteristics of central nervous system (CNS) neuroblastomas and explore the diagnostic value of CT and MRI.Materials and Methods:CT and MR imaging features of 6 patients with CNS neuroblastomas confirmed by pathology were analyzed retrospectively.Results:Six patients were enrolled,5 patients were male and 1 female,their age ranged from 3-24 years old and the average age 13.8 years old.Among them,3 cases were above tentorium,temporal lobe (1),occipital lobe (1),parietal lobe (1).And 2 cases were below tentorium,fourth ventricle (1) and the pons (1),the rest 1 case was astride left cerebellum tentorium.Two cases were cystic-solid mass,4 cases were mainly solid mass.The solid part of tumor presented iso-or hypointense on T1WI,iso-or hyperintense on T2WI,and iso-or slightly hyperintense on T2 FLAIR,after contrast,2 cases with no obvious enhancement,and 4 cases with significant enhancement.The cystic part of tumor displayed hypointense on T1WI,hyperintense on T2WI,and hypointence on FLATR sequence.The tumor were well defined and peritumoral edema was not obvious.On CT,the tumor solid compontent showed iso-or hyperdensity,calcification may be seen,and the cystic compontent showed hypo-density.Conclusions:The imaging of CNS neuroblastoma has certain characteristics on CT and MRI.It may help to the diagnosis and differential diagnosis of the disease based on tumor location,boundary,signal (or density),edema,enhancement,etc.关键词
