Abstract
✓ The authors reviewed the hospital charts of 415 pediatric patients treated for benign or malignant primary brain tumors over the past 20 years at the Children's Hospital Medical Center, Seattle. Patients' ages ranged from the neonatal period to 18 years. A shunt was placed in 152 patients (37%), 45 before and 94 after surgery. Confirmation of extraneural metastases was based on clinical and diagnostic examination. Factors analyzed as possibly influencing the occurrence of extraneural metastases were: 1) the shunt: type, valve, location, filter, and revisions; 2) extent of resection; 3) pathology; and 4) treatment regimen. Eight of the 415 patients developed extraneural metastases during life. All eight patients had a medulloblastoma (cerebellar primitive neuroectodermal tumor). These eight patients were separated into Group A (without a shunt) and Group B (with a shunt). In Group A (five patients), the mean interval from primary diagnosis to metastasis was 15 months. Two children had gross total resecti...Keywords
