title: [Traumatic genesis of an aneurysm of the pericallosal artery].
abstract: This is a report on a sac-shaped aneurysm of the pericallosal artery (that part of the anterior cerebral artery that follows the anterior communicating artery) also known as arteria pericallosa or pars postcommunicalis of the anterior cerebral artery. To exclude a fistula of the carotis cavernosus, angiography was performed that clearly showed an aneurysm of the pericallosal artery while there was no fistula of the carotis cavernosus. The vascular sac is considered to be due to trauma--this conclusion being arrived at on the basis of local conditions at the aneurysm and because of physical force having been exercised by a severe contusion of the cranium. The case was treated with success. It is discussed in this article with reference to relevant literature.
