title: The significance of the dural supply from the carotid siphon.
abstract: The dural branches from the cavernous portion of the internal carotid consists of the meningophypopseal trunk, the inferior cavernous, and the capsular arteries. These vessels have extensive anastomoses in and around the sellar area. These arteries are not usually demonstrated angiographically; therefore, when they are enlarged, a pathological lesion should be suspected. There are numerous lesions other than meningiomas associated with hypertrophy of these dural branches and the corresponding vessels involved depends on the anatomic location of the associated lesion.
