As a venous sinus, the cavernous sinus receives blood from the superior and inferior ophthalmic veins and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The cavernous sinus drains by two larger channels, the superior and inferior petrosal sinuses , ultimately into the internal jugular vein via the ...
A sphenoparietal sinus is situated under each lesser wing of the sphenoid bone near the posterior edge of this bone, [2] between the anterior cranial fossa and middle cranial fossa. [citation needed] It terminates by draining into the anterior part of the cavernous sinus. [2]
lateral wall of the cavernous sinus superomedially; clivus medially; posterior petrous face inferolaterally; Within the dural confines of the trigeminal cave, there is a continuation of subarachnoid space along the posterior aspect of the cave, representing a continuation of the cerebral basal cisterns.

The cavernous section of the internal carotid artery begins at the superior aspect of the petrolingual ligament. For surgeons and radiologists , it is important to be oriented to the location of this ligament in cases of possible dissection of the internal carotid artery, as it helps determine whether the dissection has occurred inside or ...

Symptoms may include headache, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body and seizures. The diagnosis is usually made with a CT or MRI scan ...
The intercavernous sinuses are two in number, an anterior and a posterior, and connect the two cavernous sinuses [1] across the middle line.. Intercavernous sinuses. The anterior passes in front of the hypophysis cerebri (pituitary gland), the posterior behind it, and they form with the cavernous sinuses a venous circle (circular sinus) around the hypophysis.
