We have developed a piglet model to assess chemotherapy administration directly into the fourth ventricle as a potential treatment for medulloblastoma and other malignant posterior fossa tumors. The objective of this study was to assess safety and pharmacokinetics after methotrexate infusions into the fourth ventricle. Catheters were inserted into the… (More)

The findings are as follows: cerebral atrophy; mesiotemporal T2 hyperintensity; ventriculomegaly; pathological T2 hypointensity of the globus pallidus, putamen, the head of the… (More)
