Intraoperatively the tumor was reddish colored,with jelly like thread seen below tumor leve it was adhering spinal cord seprated and removed in piece meal .histopathology revieled oligoastrocytoma spine. Spinal oligoastrocytoma are mixed glial cells having both astrocytic and oligodendroglial components and is one of most rare of spinal cord patholiges .to date only 7 cases were reported in English literature. Such tumors occur in early adolescent and young adults till middle ages 40’s, but they can however occur in children and are very difficult to identify from astrocytomas on radiological imaging .ZHUO described one in may ‘2016 as primary spinal oligoasrocytoma in craniofacial journal.
