Secondary Intraparenchymal (Intracerebral) Bleeding

A 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 ...

A 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 ...
A 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. Unlike ...
A 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 ...
A 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 flow through the MCA is ...
Non-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 side of ...
When 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 in the lateral frontal, parietal and ...
Hemorrhagic 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 bursts from damaged vessels ...
A 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 rise almost at right-angles ...
An 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 branch supplies the posterior part of the ...
Silent 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 it produces no obvious, immediate stroke symptoms that a ...
Stepwise (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 ...
A 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 not mean cancer here; it ...
Spectacular 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, aphasia, gaze ...
Early-reperfusion Middle Cerebral Artery syndrome is a cluster of neurological problems that appear within minutes to a few hours after blood flow is suddenly restored to brain tissue previously ...
Combined cortical-subcortical Middle Cerebral Artery (MCA) syndrome happens when a stroke blocks, narrows, or ruptures the large MCA trunk or many of its branches at once. Because the MCA feeds both ...
