24-year-old female with endolymphatic sac tumor. Noncontrast-enhanced T1W axial MR image reveals a heterogeneous mass lesion involving the left endolymphatic sac and petrosal bone with extension into the left internal auditory canal. T1 hyperintensities are seen within the lesion on this noncontrast study.
