Chiasmatic/hypothalamic juvenile pilocytic astrocytoma


The diagnosis of chiasmatic/hypothalamic JPA was histologically proven. There is a left remote striatocapsular infarct, that was present on transfer and the exact cause was unknown.

Key learning point: This case shows a reoccurrence of JPA in a place not related to the primary site and raises the question if this is secondary to prior leptomeningeal dissemination.
