Accessory meningeal artery: an anatomic misnomer.

The accessory meningeal artery is misnamed in view of the territory the artery supplies. The name implies that the vessel is an important addition to the middle meningeal artery in supplying the meninges. This is incorrect, because no more than approximately 10% of the blood flow of the accessory meningeal artery reaches the intracranial territory; 90% of the blood is carried to the extracranial structures. After reviewing the anatomy of the accessory meningeal artery we support the notion that the proper name of the vessel should be arteria pterygomeningica, or pterygomeningeal artery.

CT demonstration of extracranial carotid artery aneurysms.

Aneurysms arising from the extracranial carotid arteries are uncommon lesions. Clinically, they may present as lateral masses in the superior cervical area, as medial masses in the tonsillar fossa or parapharyngeal region, or as a mass palpable in both areas. Tenderness or pain may or may not be present. Pulsation is usually detectable. Embolic neurological episodes are a common event leading to discovery of these lesions. Etiologies include trauma, atherosclerosis, fibromuscular dysplasia, infection, and congenital predisposing factors. We report the CT appearance of this condition in three patients. In all three patients (four aneurysms) the CT findings were characteristic. Thus far, we have discovered only one account in the English literature that included the CT demonstration of an extracranial carotid aneurysm.

Percutaneous transluminal angioplasty of the external carotid artery.

Percutaneous transluminal angioplasty was used to treat stenotic lesions in 10 external carotid arteries in nine patients. Four representative cases are described. Nine arteries were successfully dilated. One attempt failed because the catheter could not be passed through the stenosis. Spasm of the distal external carotid artery due to guide wire-catheter manipulation was seen in six patients. No serious complications were encountered.

Department of Ophthalmology, University of Alabama, School of Medicine, Birmingham.

Evaluation of over 255 patients with sellar and parasellar lesions allowed study of the computed tomographic (CT) appearance of the cavernous sinus. Optimal visualization of the cavernous sinus was obtained with continuous contrast enhancement of both axial and coronal tomograms. The coronal projection provided imaging of cranial nerves with the cavernous sinus. The intracavernous carotid artery was seen only if it were calcified or encased by tumor extending into or invading the sinus. CT criteria suggesting an abnormal cavernous sinus are: (1) asymmetry of size, (2) asymmetry of shape, particularly the lateral wall, and (3) focal areas of abnormal density within the sinus. The neurovascular anatomy of the cavernous sinus is reviewed and correlated with CT findings. Discrepancies between anatomic and CT appearance are discussed.

Stenting of symptomatic stenosis of the intracranial internal carotid artery.

Percutaneous balloon angioplasty has been reported to be useful in the treatment of intracranial atherosclerotic arterial stenoses; however, arterial dissection with increased risk of stroke has limited its widespread implementation. Although vascular stenting has improved the outcome of similar procedures in the extracranial vasculature, its intracranial application has been limited by the lack of suitable stents. We report a case of successful percutaneous stenting of a symptomatic intracranial carotid artery using a second-generation, flexible, coronary stent.
