Intracranial pilocytic astrocytoma with spinal drop metastasis: A case review, discussion of its current management and related literature

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. It within the ventricle. In this report, we described our experience with cranial pilocytic 14-year-old child, who initially treated near total decompression of tumor. Four and half years later, recurrence primary tumor obstructive hydrocephalus occurred for which he underwent ventriculo-peritoneal shunt followed by re-excision. As further treatment was being evaluated radiotherapy view at site, got detected to have significant spinal drop metastasis seen on MRI Spine. Finally, craniospinal irradiation (CSI).
