Cavernous sinus

From WikiLectures

Schéma sinus cavernosus.

The sinus cavernosus is a venous sinus in the dura mater at the base of the skull on either side of the sella turcica.

It has a spongy structure, due to the numerous trabeculae that penetrate it. Through v. opthalmica it is connected to blood draining from the facial area. Some purulent infections in the face (e.g. furuncle, cheilitis) can thus spread to this area and cause severe intracranial infections and thrombosis of the sinus.
