title: Posttraumatic dissecting aneurysm of the anterior cerebral artery: case report.
abstract: A case of cerebral infarction in the territory of the anterior cerebral artery after a minor head injury is reported. It is possible that direct or mechanical damage by the edge of the falx or stretching and shearing of the anterior cerebral artery after an acute shift of the corpus callosum caused the localized lesion of the left anterior cerebral artery. We think that this mechanical injury caused a dissecting aneurysm or a cerebral arterial dissection, which was diagnosed by sequential angiographic changes.
