ABSTRACT
@#Objective To investigate the clinical features, therapeutic strategy and prognosis of pediatric benign cerebellar astrocytomas (BCAs). Methods 101 children with BCAs diagnosed histopathologically were analyzed retrospectively and followed up. Results There were 50 boys and 51 girls with a median age of 9.8 years old. The sizes of tumors were 3～7.5 cm. 46 cases were with solid-tumor, 24 with the tumor in the cyst, 31 with the cysty in the tumor. 39 cases were located in cerebellum vermis, 58 cases were in the cerebellar hemisphere and 9 cases were adhesive with brain stem located in the forth ventricle. 92 cases were total removed and 9 cases were subtotal removed. 87 patients were followed up for 1～5 years, and all of them has survived, without radiotherapy or chemotherapy. Conclusion Pediatric benign cerebellar astrocytomas mostly grows in cerebellar hemisphere， also in vermis frequently. Neuroimaging and pathology may conduce to the diagnosis. Microsurgical resection may result in optimal outcome.
