Read articleMixed intracerebral–intraventricular bleeding (MIIVB) is a medical emergency in which blood escapes from damaged brain-parenchymal vessels, collects inside the brain tissue itself (an intracerebral hemorrhage), and...
Read articleA secondary intraparenchymal bleed (secondary ICH) is fresh bleeding that pools inside the brain’s substance because of an identifiable underlying problem—for example a ruptured arteriovenous malformation,...
Read articleA primary intraparenchymal bleed—better known as a primary intracerebral hemorrhage (ICH)—occurs when a weakened vessel inside the brain suddenly ruptures and floods the surrounding tissue with...
Read articleA cortical–subcortical, or lobar, intracerebral hemorrhage (ICH) is a bleeding event that begins in the gray-matter cortex and immediately spreads into the neighboring white-matter beneath it....
Read articleA putaminal (deep ganglionic) hemorrhage is bleeding that begins inside the putamen—one of the basal-ganglia nuclei that sits alongside the internal capsule. Because the lenticulostriate perforators...
Read articleA transient ischemic attack (TIA) in the territory of the middle cerebral artery is sometimes called “MCA transient ischemia” or “MCA-syndrome TIA.” It happens when blood...
Read articleNon-dominant-hemisphere MCA syndrome occurs when a blockage or severe narrowing stops blood flow through the main branch of the middle cerebral artery that supplies the non-language-dominant...
Read articleWhen the left (language-dominant for ~95 % of right-handed people) middle cerebral artery is suddenly blocked by a clot or ruptures and bleeds, vital brain tissue...
Read articleHemorrhagic MCA syndrome is a type of intracerebral hemorrhage (ICH) that occurs inside the brain tissue supplied by the middle cerebral artery. Blood suddenly leaks or...
Read articleA deep, or lenticulostriate, infarct is a tiny area of dead brain tissue caused by the blockage of one or more lenticulostriate arteries—small penetrating branches that...
Read articleAn inferior-division infarct of the Middle Cerebral Artery (MCA) is an ischemic stroke that blocks blood flow to the lower (inferior) branch of the MCA. This...
Read articleSilent cortical infarct is a small area of brain tissue in the outer (cortical) layer that has died because its blood supply was cut off, yet...
Read articleStepwise (lacuno-cortical) progression Middle Cerebral Artery (MCA) syndrome is a pattern of ischemic stroke in which small, deep (“lacunar”) infarcts and superficial cortical branch infarcts occur...
Read articleA malignant frontal infarct is a very large stroke that destroys brain tissue mainly in the frontal-lobe territory supplied by the middle cerebral artery. “Malignant” does...
Read articleSpectacular Shrinking Deficit (SSD) is an unusual stroke pattern first described by Mohr in the mid-1980s. A patient presents with a dramatic, classic MCA stroke—dense hemiplegia,...
