B, Axial T2-weighted image shows the heterogeneity of the lesion with marked hypointense (longer arrow), isointense, and hyperintense (shorter arrow) areas. C, Postcontrast axial T1-weighted image shows marked heterogeneous enhancement of the isointense and hyperintense areas seen on the T2-weighted image (shorter arrow) and no enhancement of the hypointense areas (longer arrow). D, CT image shows a heterogeneous tumor with hyperattenuation.
