Delayed radiation-induced stroke mimics recurrent tumor in and adolescent with remote history of low-grade brainstem glioma

A 13-year-old female was diagnosed with a ponto- medullary brainstem glioma and following unsuccessful treatment with chemotherapy, underwent focal photon intensity modulated radiation therapy that resulted in a favorable response. Ten years later, the patient presented with acute onset left-sided hemiplegia and headaches. Magnetic resonance imaging (MRI) at presentation showed a large contrast- enhancing lesion with surrounding vasogenic edema and reduced diffusivity on diffusion- weighted imaging most concerning for a high grade secondary malignancy (Figure 1).
