Figure 6c. Brainstem glioma after craniopharyngioma. (a, b) Sagittal (a) and axial contrast-enhanced (b) T1-weighted MR images obtained in a 10-year-old girl show an isointense, heterogeneously enhancing suprasellar mass (arrow), a finding that is suggestive of craniopharyngioma. The tumor was partially resected. (c) Follow-up sagittal T1-weighted MR image demonstrates no progression of the mass. Residual calcifications were seen at CT. (d) Axial contrast-enhanced T1-weighted MR image obtained 8 years later shows a heterogeneously enhancing mass that involves the upper brainstem. Stereotactic biopsy revealed high-grade glioma.
