Selected images from an MRI of the posterior fossa demonstrates a large cystic mass with peripheral nodular enhancement. It appears to be arising from the left hemisphere, displacing and compressing the fourth ventricle. Given the patients age, the ventricles appear enlarged in keeping with hydrocephalus.
Case Discussion
These are fairly typical appearances of a pilocytic astrocytoma - a cystic mass with mural enhancing nodule in a child.
