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 c...

150 I T IS GENERALLY appreciated that modulloblastoma, perhaps the most rapidly growing and highly malignant of all brain neoplasms, commonly involves the corebelhum and fotmrth ventricle of young children. Umifortimnatoly, the gloomy outlook for this tumor has too often spread to encompass all brain tumors in childhood and overshadow the fact that cerebollar astrocytoma, a tuITlO at the opposi...

Pilomyxoid astrocytomas (P.M.A) are new class of Pilocytic Astrocytoma (P.A.) which typically have their origin in hypothalamus and chiasmatic region. There are very few case reports of PMAs arising from cerebellum. Their imaging features are similar to PA but they behave more aggressively than PA. The authors report a case of 10 year old male child who presented with right cerebellar tumour di...

Neurologically, BRAF V600E mutation was detected in cerebellar anaplastic pilocytic astrocytoma [6], ganglioglioma [7], desmoplastic infantile astrocytoma [8], indeterminate cell tumor and interdigitating dendritic cell sarcoma [9]. Hematologically, BRAF V600E mutation was also detected in multiple myeloma [10] and several leukemias (hairy cell, chronic lymphocytic, prolymphocytic and acute lym...

Abstract Gliomas of the cerebellum are rare in adults, and their natural history and clinical behavior are not well known. Because cerebellar glioma is not usually diagnosed until clinical symptoms have appeared, no reports have described the developmental process of new cerebellar gliomas. We describe a case of de novo cerebellar anaplastic astrocytoma in which the developmental process was de...

INTRODUCTION Cerebellar high-grade astrocytoma is uncommon. Although more prone to present cerebrospinal fluid dissemination, the cerebellar location is not particularly related to the occurrence of extra-cranial metastases, which are also unusual in supratentorial malignant gliomas. CASE REPORT A 46 year-old man with cerebellar anaplastic astrocytoma who developed pancytopenia due to extensi...

This patient presented with a rare case of metachronous, multicentric gliomas first manifesting as headache and nausea in 1983 when he was an 8-year-old boy. Computed tomography revealed a cerebellar tumor and the tumor was subtotally resected. The histological diagnosis was pilocytic astrocytoma, and radiation therapy to the posterior fossa and chemotherapy consisting of nimustine hydrochlorid...
