ABSTRACT
Objective To discuss MRI and pathological features of intracranial hemangioblastoma.Methods MRIdata of 26 cases of hemangioblastoma confirmed with operation and pathology were analyzed retrospectively.Results There were 22 cases with single lesion and multiple lesions in 4 eases.And a total of 31 lesions located in the posterior cranial fossa,including 14 lesions in right cerebellar hemispheres,9 lesions in left cerebellar hemispheres,2 lesions in cerebellar inferior vermis,4 lesions in medulla oblongata,and 2 lesions in fourth ventricle.Ninteen lesions showed cystic nodular type,1 lesion was cystic type,11 lesions showed parenchymal type or partial parenchyma type.Cystic lesions showed long T1 and long T2 signal,T1WI of solid area showed slightly long T1 and slightly long T2 signal,of which 12 lesions were slightly shorter T1 signal.Solid areas significantly enhanced,cystic area had no enhancement,but cystic wall of 3 cystic nodular lesions were slightly enhanced.DWI of solid areas showed low signal.MRS showed the peak of Cho obviously increased,and the peaks of Cr and NAA obviously decreased or nearly disappeared,and the high peak of lipids and lactate were observed.Conclusion The conventional and functional MRI of intracranial hemangioblastoma have some characteristics,MRI has a great value in the diagnosis and localization of intracranial hemangioblastoma.
