Abstract

• Reliable diagnostic methods for head and neck vascular lesions are needed. The technique of dynamic computed tomography (CT) is used to delineate two aberrant subclavian arteries, one carotid artery aneurysm, and one angiofibroma. Five or six 4.8-s CT scans were obtained sequentially, separated by a 1.2-s interscan interval. Computer-generated iodinated contrast concentration (CT number) v time curves showed rapid influx of contrast, high peak density, and rapid uninterrupted contrast runoff. Simultaneous bone and soft-tissue visualization at the time of peak contrast enhancement provides excellent delineation of the malformations and angiofibroma. The technique is noninvasive, and it eliminates the potential complications of arteriography and biopsy. We conclude that dynamic CT is an excellent method for diagnosis of head and neck vascular lesions.
