Forth ventricle hematoma in a eight-year-old child.

We report the case of a 4th ventricle hematoma due to rupture of an angioma localized in the cerebellar vermis, in an eight-year-old child. Only seven cases of a vascular malformation in such a localization, angiographically and/or pathologically verified, have been previously reported. The girl died, in spite of prompt surgical treatment. Also the clinical presentation of this kind of case is very rare.
