Overview

Brain MRI is helpful in the diagnosis of atypical teratoid rhabdoid tumor. On MRI, atypical teratoid rhabdoid tumor is characterized by iso- to slight hyperintensity on T1-weighted imaging and hyperintensity on T2-weighted imaging. There is heterogeneous enhancement on contrast administration.

MRI

  • Brain MRI may be helpful in the diagnosis of atypical teratoid rhabdoid tumor.
  • Findings on MRI suggestive of atypical teratoid rhabdoid tumor are tabulated below:[1]
MRI component Findings

T1
