Crynodeb:Medulloblastoma, the most frequent pediatric brain tumor, has a known propensity for subarachnoid dissemination. Spinal metastases indicate a poor prognosis. Intraventricular spread is much less common. We report a case of primary intraventricular dissemination with precocious puberty as the first clinical symptom due to a metastasis at the infundibulary stalk. This has not been reported so far as initial symptom of a medulloblastoma. Furthermore, we encountered an unusually mild contrast enhancement of the spinal and intraventricular metastases. Delayed scanning after contrast administration and FLAIR sequences proved to be particularly valuable in this case.
