Intraventricular haemorrhage caused by the rupture of a dural arteriovenous malformation of the middle cranial fossa.

Dural arteriovenous malformations of the middle cranial fossa are very rare. Venous drainage flows either through superficial leptomeningeal veins or through the sphenoparietal, sphenopetrous and/or sphenobasilar sinuses. They often have an aggressive course and therefore poor outcome. It is essential to analyse and understand the angioarchitecture of the dural arteriovenous malformations in order to select and plan the correct treatments. We describe an exceptional case of intraventricular haemorrhage caused by the rupture of a dural arteriovenous malformation of the middle cranial fossa. To our knowledge, this is the first case report of such characteristics described in the literature.
