<unk> s are aneurysms in the small penetrating blood vessels of the brain. They are associated with hypertension. The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum. As with any aneurysm, once formed they have a tendency to expand and eventually rupture, in keeping with the Law of Laplace.
