Spinal Seeding of Cerebellar Pilocytic Astrocytoma and Spontaneous Regression of Tumor: a Case Report

Cerebellar pilocytic Astrocytoma is a benign tumor, acounts for 80% of all cerebellar Astrocytoma, and has a relatively good prognosis. This tumor usually presents with Ataxia and in the case of hydrocephaly with raised intracranial pressure signs such as headeach, and vomiting. Treatment of this tumor is complete resection and if hydrocephally is present V.P. shunt should be inserted. In the case of recurrence or tumor seeding radiotherapy is recommended. Seeding of cerbellar Astrocytoma has been reported rarerly. Spontaneous regression of chiasmatic pilocytic Astrocytoma associated with neurofibromatosis type I has been reported but Spontaneous regression of cerebellar Astrocytic tumor without neurofibromatosis has been reported very rarely in the literature. In this report a young patient with seeding of cerebellar Astrocytoma in the lumbosacral region with severe neurological deficit who has recovered spontaneously without any treatment is presented.. This case is intresting for both seeding and spontaneous regression of tumor.
