Introduction
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].
