PMA is a rare tumor in adults, and most certainly it is extremely rare in the spinal cord .It was first reported in a pediatric group of patients [1].It has been added under pilocytic astrocytoma PA subtype according to WHO CNS tumor classification in 2007 as grade II, with variant histological characteristics and a more aggressive behavior [2]. PMA predominantly occurs in infants and young children and is most commonly located in the hypothalamic/chiasmatic region and shares other locations with pilocytic astrocytoma like the thalamus, temporal lobe, brain stem and cerebellum [3].
