  3. Intracerebral hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracerebral_hemorrhage

    Hemorrhagic stroke may occur on the background of alterations to the blood vessels in the brain, such as cerebral arteriolosclerosis, cerebral amyloid angiopathy, cerebral arteriovenous malformation, brain trauma, brain tumors and an intracranial aneurysm, which can cause intraparenchymal or subarachnoid hemorrhage.

  4. Transcranial Doppler - Wikipedia

    en.wikipedia.org/wiki/Transcranial_Doppler

    Two methods of recording may be used for this procedure. The first uses "B-mode" imaging, which displays a 2-dimensional image of the skull, brain, and blood vessels as seen by the ultrasound probe. Once the desired blood vessel is found, blood flow velocities may be measured with a pulsed Doppler effect probe, which graphs velocities over time.

  5. Intracranial hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracranial_hemorrhage

    A subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Trauma can also cause SAH when the arteries and veins coursing through the subarachnoid space are ruptured.

  6. Intraventricular hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intraventricular_hemorrhage

    Brain contusions and subarachnoid hemorrhages are commonly associated with IVH. [20] The bleeding can involve the anterior communicating artery or the posterior communicating artery. In both adults and infants, IVH can cause dangerous increases in ICP, damage to the brain tissue, and hydrocephalus. [9] [21]

  7. Xanthochromia - Wikipedia

    en.wikipedia.org/wiki/Xanthochromia

    The most common cause for bleeding into the subarachnoid space is a subarachnoid hemorrhage from a ruptured cerebral aneurysm. [ 3 ] The most frequently employed initial test for subarachnoid hemorrhage is a computed tomography scan of the head, but it detects only 98% of cases in the first 12 hours after the onset of symptoms, and becomes less ...

  8. Lumbar puncture - Wikipedia

    en.wikipedia.org/wiki/Lumbar_puncture

    Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and

  9. Terson syndrome - Wikipedia

    en.wikipedia.org/wiki/Terson_syndrome

    A subarachnoid hemorrhage brought on by a ruptured aneurysm, or less frequently, other forms of brain hemorrhages (such intracerebral or subdural hemorrhages), is usually the origin of the abrupt increase in intracranial pressure that frequently precedes the onset of Turner's syndrome.
