Update on the natural history of infratentorial cavernous malformations
Abstract
Infratentorial cavernous malformations are still a source of serious controversies in neurosurgery and their natural history and treatment are intensely debated in literature. Recent studies suggest that symptomatic infratentorial cavernous malformations have a more aggressive clinical outcome than the supratentorial ones (the risk of hemorrhage is approximately 30 times that of the supratentorial cavernomas) The optimal therapeutic approach of infratentorial cavernomas need a good understanding of the natural history and also the characteristics that may influence the associated neurological risk, like the patient status at admission, the localization and the genetics of the malformation. Many studies have been published in the last decades to enlight the clinical aspects and the natural history of these vascular malformations. The purpose of this analysis is to make a literature review of the morbidity risk associated to cavernous malformations and their influence on the treatment plan.
