In a series of 180 patients affected by brain stem tumors, 70 cases of children up to 16 years are analyzed. Diagnosis was made with clinical examinations, neuroradiological tests and, in 20 cases, with surgical explorations. A description is made concerning the clinical status with regard to site, extension and features of the tumor. Then the authors analyze statistically the survival of such patients in connection with clinical symptomatology, the radiological picture, medical treatment, radiation and/or surgical therapy either in the few cases of subtotal removal of the tumors, or in the more numerous cases of palliative procedures such as intra- and extra-thecal CSF shunting.
