Atypical MRI appearance of desmoplastic infantile ganglioglioma.

We report the atypical MRI features and histopathological findings of a desmoplastic infantile ganglioglioma in an 8-year-old girl. The mass was predominantly solid with a large, solid, non-enhancing exophytic component. The adjacent brain showed cortical necrosis and white-matter gliosis, suggesting earlier hypoxia.
