Diffusion tensor imaging in evaluation of posterior fossa tumors in children on a 3T MRI scanner.

However, conventional MRI features like diffuse cerebellar involvement with ill-defined margins, involvement of the cerebellar gray matter, and associated leptomeningeal enhancement can help in differentiating cerebellitis (either inflammatory or demyelinating) from neoplasms.[ 14 ] Also, a close follow-up MR imaging may show complete resolution of the lesions, sometimes healing with residual cerebellar atrophy.[ 14 ] On DTI analysis, inflammatory cerebellitis showed a trend toward relatively low RA maximum (RA-max), VR maximum (VR-max), cP maximum (cP-max), and RD mean (RD-mean).
