Mixed 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...

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...

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...

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...

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...

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...

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...

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...

Hemorrhagic MCA syndrome is a type of intracerebral hemorrhage (ICH) that occurs inside the brain tissue supplied by the middle cerebral artery. Blood suddenly...

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...

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...

Silent cortical infarct is a small area of brain tissue in the outer (cortical) layer that has died because its blood supply was cut...

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...

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....

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...

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...

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...

A dominant-hemisphere MCA infarct is an ischemic stroke that blocks blood flow through the middle cerebral artery on the side of the brain that...

A middle cerebral artery infarct occurs when blood flow through the MCA is blocked, depriving its downstream brain tissue of oxygen and nutrients. In...

A partial, branch-selective MCA infarct is a stroke that injures only one division or perforating branch of the brain’s largest “workhorse” artery. Because different...
