[Association of venous angioma and cavernoma of the posterior fossa].
BACKGROUND
Association of venous angioma to cavernous malformation is rare. If bleeding occurs, it must be assigned to the cavernous malformation.


METHODS
A 4 year-old boy suffered from an acute ataxia. Investigation showed a venous angioma and a cavernoma malformation in the posterior fossa. The patient was admitted again at the age of 8 years for a new episode of acute ataxia due to cerebellar hematoma. A conservative treatment was settled because of the risk of venous infarction.


CONCLUSIONS
Venous angiomas are rarely symptomatic and are considered as normal venous variants. Indeed, the cavernomas are true malformations with a high bleeding potential. When both lesions are associated and bleeding occurs, only the cavernous malformation has to be removed if surgically accessible.
