Spinal metastasis in primitive neuroectodermal tumors (medulloblastoma) of the posterior fossa: evaluation with CT myelography and correlation with patient age and tumor differentiation

Pediatr Neurosci. 1985;12(3):157-60. doi: 10.1159/000120239.

Abstract

Twelve consecutive children with primitive neuroectodermal tumors of the posterior fossa (PNET-PF) were evaluated for spinal metastases with CT metrizamide myelography (CTMM) in the early postoperative period. Metastases were identified in 5 children (42%) and all were noted to have deposits in the thoracic region. All children with metastases were less than 3 years old and had differentiated PNET-PF.
