[Supratentorial cavernous malformations in an Argentinian institution: experience with surgical treatment].

Introduction: Cavernous malformations are vascular malformations of the central nervous system formed by a group of capillaries not covered by pia mater and communicated to the vascular system at very low pressure with very slow flow. Surgery or radiosurgery are the treatment modalities.
