Pilocytic astrocytoma (PA) is a low grade benign tumor, commonly occurs in Cerebellum (42-60%), Optic & hypothalamic region (9-30%), Brain Stem (9%). They rarely spread.

As further treatment was being evaluated for radiotherapy in view of recurrence at the primary site, he got detected to have significant spinal drop metastasis seen on MRI Spine. Finally, he underwent craniospinal irradiation (CSI). Keywords: Pilocytic astrocytoma, Craniospinal irradiation, Spinal
