| Abstract: | Objective： To study the MR features of the pilocytic astrocyma.Methods： The clinical pathology confirmed 15 cases of pilocytic astrocyma,its MR and pathological results were analyzed.Results： 15 patients with pilocytic astrocyma including cerebellar vermis in 8 cases,7 cases of cerebellar hemisphere;4 cases of cystic PA,6 cases of PA for the solid and cystic,4 cases of PA is solid,and 1 case of solid with small cystic changes,the enhanced lesion solid wall and an obvious enhancement,cystic part of no enhancement,peritumoral edema with mild or no edema.Conclusion： MR pilocytic astrocyma have certain performance characteristics,combined with clinical,can have a preliminary diagnosis. |
