Definition: a paired dural venous sinus on either side of the sella turcica, the two being connected by anastomoses, the anterior intercavernous sinus (sinus intercavernosus anterior [TA]) and posterior intercavernous sinus [TA] (sinus intercavernosus posterior [TA]), in front of and behind the hypophysis, respectively, thus making the circular sinus; the cavernous sinus is unique among dural venous sinuses in being trabeculated; coursing within the sinus are the internal carotid artery and the abducent nerve. The cavernous sinus is sometimes described as a plexus because of its unique internal structure.
Synonym(s): sinus cavernosusTA
