Abstract
The occurrence of calcifications in the large arteries at the base of the brain was examined by an improved radiological technique in autopsy specimens from 25 patients. Calcifications were found to be common in the vertebral and internal carotid arteries but rare in the other large basal arteries of the brain. The ophthalmic and middle meningeal arteries in autopsy specimens from 10 patients were also investigated and were found to contain calcifications, commonly in their most proximal intracranial portions. Calcifications were often present in arterial segments with no or slight arteriosclerotic intimal changes. The degree of calcification is not a good measure of the degree of arteriosclerotic intimal changes in intracranial arteries. Mechanical factors probably play a part in the development of calcifications in intracranial arteries.
