Abstract：Objective To analyze the routine MRI and DWI(Diffution Weighted Imaging), T2FLAIR(T2 Fluid-attenuated Inversion Recovery) feature of medulloblastoma, in order to optimize diagnostic accuracy of medulloblastoma.Methods 18 cases of medulloblastoma confirmed by histopathology were analyzed retrospectively on routine MRI, DWIand T2FLAIR findings.Results Among 18 cases with medulloblastoma, 14 lesions located at the cerebellar vermis, and the other 4 cases were in the cerebellar hemisphere;medulloblastomas showed as solid tumors in 10 patients, cyst-solid masses in 8 patients;6 cases growed along the hole;ahead of cerebrospinal fluid in 10 cases.The solid components presented with subtle or medium enhancement in 6 cases,marked enhancement in 10 cases, and significantly enhancement in 2 cases.All of the 18 cases were with hyper-intense signal on DWI;14 cases were with isointense signal and 4 cases with hyper-intense signal on T2FLAIR.Conclusion The routine MR imaging of medulloblastoma can cause some cases misdiagnosis, combination of DWI and T2FLAIR may help to obviously improve imaging diagnostic accuracy.
