Female, 12 years old, with history of astrocytoma status post chemotherapy. Off therapy evaluation. Redemonstrated are findings secondary to suboccipital approach surgery. An exophytic lesion projecting from the left anterolateral aspect of the medulla is stable in size and morphology. Internal to this tissue, there is a region of intrinsic T1 hyperintensity with minimal if any superimposed true enhancement.No new intracranial lesions or pathologic intracranial enhancement is seen. A small linear focus of T2 hyperintensity adjacent to the right frontal horn is stable. Prominence of the cerebellar fissures is compatible with volume loss. No abnormal fluid collections are seen. The ventricles are stable and normal in size.
