Neuro Child + Ataxia + Mural Nodule = ?

Classic case scenario in USMLE where a child or a young adult presents with cerebellar ataxia and other cerebellar signs + headache + CT scan or MRI showing a cystic lesion with "mural nodule" then your diagnosis should be Pilocytic Astrocytoma which is a grade I astrocytoma with favorable prognosis.
It's the most common primary CNS in children followed by craniopharyngioma and ependymoma.
