Sixty-six children with intrinsic brainstem gliomas diagnosed between 1980 and 1986 underwent radical surgical resection. Retrospective analysis permitted classification of tumors into four categories: diffuse, focal, cystic and cervicomedullary. All 27 patients with diffuse tumors had malignant neoplasms, were not benefitted by surgery and died within 12-18 months. Five of nine cystic tumors, three of five focal tumors and twenty of twenty-four cervicomedullary tumors had low grade histopathology and are alive one to six years postoperatively. The authors propose a clinical-neuroradiological criteria that accurately predict which patients with brainstem tumors are likely to benefit from radical surgical intervention

The author reviews current concepts involving the etiology, pathogenesis, and treatment of hydromyelia. A critical evaluation of current surgical approaches in relation to the type of hydromyelia present is discussed

A retrospective examination of brain tumors in infants less than a year of age was undertaken by reviewing their charts and CT scans. In contradistinction to brain tumors found in older children, most tumors were supratentorial in location. The most common histologic types included: astrocytoma, ganglioglioma and primative neuroectodermal tumors. Apart from their larger size at the time of presentation, these tumors were radiologically and pathologically similar to analogous tumors found in adults

Between 1970 and 1986, 20 patients were treated for the 'Slit-ventricle syndrome'. Six patients had intermittent proximal shunt malfunction and 14 children had increased intracranial pressure with normal shunt function. All of the children in the second group had a relatively small calvarium. Treatment consisted of proximal shunt revision in the first group and a calvarial expansion procedure in the second. The authors discuss the differential diagnosis of the slit-ventricle syndrome and offer guidelines to appropriate treatment
