UNASSIGNED: @entity2758 ( @entity2758 ) are rare, representing only 7-15% of @entity7026 . The concentration of eloquent neurological structures and the high rate of @entity548 presentation of @entity2758 in this location complicate the management of such lesions. New therapeutic options, especially in endovascular therapy, have fundamentally modified the treatment strategy and also the outcome of posterior fossa @entity2758 . Between 1999 and 2013, baseline, clinical and angiographic data of @entity7026 were prospectively collected. We analyzed data from @entity1 treated for a posterior fossa @entity2758 , focusing on risk factors for @entity548 , and clinical and angiographic outcomes. Sixty-nine @entity1 (mean age 34years, male to female ratio 2:1) were consecutively treated for an infratentorial @entity2758 . Fifty-seven presented with @entity548 , six with focal @entity51 , and the remaining six @entity1 were diagnosed incidentally. The Spetzler-Martin grade was <3 in 39 (56.5%) @entity1 . Associated @entity439 were noted in 43.5% of @entity1 . All @entity1 were treated using endovascular procedures, associated with microsurgical resection in nine @entity1 and with stereotactic radiosurgery in six. Mean follow-up was 28.5months, with angiographic exclusion of the @entity2758 in 72.5% of @entity1 ; 21.7% of @entity1 presented a modified Rankin Score    3 at follow-up. Endovascular embolization seems to be a secure approach for posterior fossa @entity2758 although a large number of sessions are necessary to achieve complete obliteration. Multi-disciplinary discussion and management is crucial to obtain the best cure rate without increasing procedural risks.
