Figure 1: Opticochiasmatic-hypothalamic pilocytic astrocytoma in a child with growth failure due to isolated growth hormone deficiency. Coronal FLAIR (a) and T1W post contrast (b) MR images show a large heterogeneous enhancing sellar-suprasellar mass lesion (arrow) with resultant upstream obstructive hydrocephalus. Note, it is difficult to differentiate whether the tumor originates from chiasma or hypothalamus, as typically both of these structures are involved. Post surgical biopsy proved astrocytoma
