Brain tumors take an important place among the most frequent malignancies of children. Compared with the adult age group, posterior fossa tumors are seen in higher percentage in children (30–56%). Low grade astrocytomas, medulloblastomas and epandymomas are seen frequently, dermoid tumors, rhabdoid tumors, teratomas, high grade gliomas are seen occasionaly, meningiomas, metastasis are seen rarely in this age group. 73 child cases with posterior fossa tumor were operated in Neurosurgery Departments of Cerrahpaça Medical School and Baklrkoy Psychiatry and Neurological Science State Hospital between 1988–2000. In 37 cases (51 %) cerebro-spinal fluid was drained with external ventricular drainage preoperatively. 48 cases (66%) were operated in prone, 22 cases (30%) in sitting, 3 cases (4%) in lateral decubitis position. The results of 30 (41 %) cases were medulloblastoma, 28 (38%) cases were low grade astrocytoma, 11 (15%) cases were epandymoma, 2 (3%) cases were theratoid-rhabdoid tumor, 2 (3%) cases were metastasis. Ventriculo-peritoneal shunt was applied to 10 (27%) cases of 37 cases whose cerebro-spinal fluid drained via external ventricular drainage method; again ventriculoperitoneal shunt was applied to 9 (25%) cases of 36 cases whose cerebro-spinal fluid was not drained. For low grade astrocytoma cases no adjuvant therapy was applied postoperatively, for the rest of the cases adjuvant radyotherapy and! or chemotherapy was applied. Our results were reviewed in association with the literature. Anahtar Kelimeler : Child, posterior fossa, tumors
