Washington University Experience | VASCULAR | Herniation, tonsillar | 13A Hernation, tonsillar vs artifact (Case 13A)
Cases 13A-E In this group I have placed cases which do not show compelling tonsillar herniation. These cases lack a relevant clinical history and lack of associated findings including gross or microscopic hemorrhages in the cerebellum or medulla.
