Complete myelographic evaluation of spinal metastases from medulloblastoma.

Abstract

Patients (26) with medulloblastoma had complete myelography and spinal fluid cytology and tests for polyamine levels in the evaluation for spinal metastases. The nature and location of abnormalities are presented. Metrizamide is safe and effective for complete myelography in children. The usefulness of myelography in detecting spinal metastases at the time of initial diagnosis (11%) and at the time of 1st intracranial recurrence (33%) is discussed.
