Abstract

Cerebral aneurysms are of greater frequency than is ordinarily considered. The hemorrhage from a ruptured aneurysm is too easily diagnosed as cerebral or meningeal apoplexy, and the origin of the hemorrhage is not verified by necropsy. Cortical herniation into dural sinuses is another condition that occurs rather frequently but is not commonly recognized. It is found in association with increased intracranial pressure. Neither condition often presents localizing diagnostic symptoms, but these may occur and be significant. This report of ten cases of cerebral aneurysm, eight of which were verified by necropsy, is prompted because of the application of internal carotid ligation in two and the discovery of an unusual complication of herniation of the motor cortex into pacchionian bodies in another. Before presentation of the case reports, a few of the significant points pertaining to the two subjects will be discussed briefly.
