    en.wikipedia.org/wiki/Middle_cerebral_artery...

    Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.

    Diagram of cerebral aneurysm. Cerebral aneurysms are classified both by size and shape. Small aneurysms have a diameter of less than 15 mm. Larger aneurysms include those classified as large (15 to 25 mm), giant (25 to 50 mm) (0.98 inches to 1.97 inches), and super-giant (over 50 mm). [3]

  4. Dense MCA sign - Wikipedia

    en.wikipedia.org/wiki/Dense_MCA_sign

    The dense MCA sign is a dense artery sign observed on non-contrast computed tomography (CT) of the brain and is an important early marker of acute ischemic stroke involving the middle cerebral artery territory. [1] It refers to an abnormally increased attenuation (hyperdensity) of the MCA, reflecting an intraluminal thrombus or embolus.

    Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).

    en.wikipedia.org/wiki/Middle_cerebral_artery

    The middle cerebral artery (MCA) is one of the three major paired cerebral arteries that supply blood to the cerebrum. The MCA arises from the internal carotid artery and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex .

    Ruptured 7 mm left vertebral artery aneurysm resulting in a subarachnoid hemorrhage as seen on a CT scan with contrast. Diagnosis of a ruptured cerebral aneurysm is commonly made by finding signs of subarachnoid hemorrhage on a computed tomography (CT) scan.

  9. Subarachnoid hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Subarachnoid_hemorrhage

    An aneurysm may be detected incidentally on brain imaging; this presents a conundrum, as all treatments for cerebral aneurysms are associated with potential complications. The International Study of Unruptured Intracranial Aneurysms (ISUIA) provided prognostic data both in people having previously had a subarachnoid hemorrhage and people who ...
