"Pathophysiology"
"Associated features depend upon the underlying cause and relate to hydrocephalus, raised intracranial pressure and mass effect on optic nerves, cranial nerves, pituitary or brainstem. They therefore include macrocephaly, ataxia, developmental delay, optic disc pallor or atrophy, and endocrinopathy 2."
"other cysts (e.g. septum pellucidum cyst, cavum velum interpositum cyst)"
"masses within or impinging on the third ventricle (e.g. craniopharyngioma, choroid plexus papilloma)"
"spasmus nutans: self-limiting disorder of young infants; prominent asymmetric nystagmus is the dominant feature; no structural CSF abnormality"
