We conclude that hypodensity of the cerebral white matter in patients with transient ischemic attack or minor stroke is associated with an extra risk of future stroke, from large as well as from small vessels, and particularly in patients under 70 years old; this increase of risk is independent of other risk factors for stroke.

Hyperdensity in the basal ganglia contralateral to the hemichorea on her head CT is consistent with what has been reported in the literature. Brain MRI seems more commonly used which in those cases showed T1 putamen hyperintensity contralateral to the side of hemichorea or T2 hypodensity in the contralateral involved site [1, 4, 9] .

Hyperdensity on a CT head may be due to the presence of blood, thrombus or calcification: A hyperdense middle cerebral artery (MCA) is sometimes noted in total anterior circulation strokes (TACS) and indicates the presence of a large thrombus within the vessel. Examine the brain tissue. Sometimes you can differentiate gray and white matter along the cerebral convexity.

2021-04-10 · The hyperdensity noted in the initial CT had completely disappeared. The minor residual neurological deficits noted post-ictally (Todd's paralysis) completely resolved over 24 hours. As the CT changes were unilateral, we presumed that the ictal activity originated from the left hemisphere.

Brain MRI seems more commonly used which in those cases showed T1 putamen hyperintensity contralateral to the side of hemichorea or T2 hypodensity in the contralateral involved site [1, 4, 9] .

Contrast will not leak into the brain unless this barrier is damaged. Enhancement is seen when a CNS tumor destroys the BBB. The hyperdense MCA sign is seen as focal hyperattenuation of the M1 segment of the MCA on NCCT of the brain (Fig. 1). It is one of the earliest visible radiological signs of acute ischaemic stroke, as it can be seen within 90 minutes after stroke onset. Brain imaging is distinctive. Ultrasonography shows echogenicity of periventricular white matter, a frequent finding in early infantile white matter degenerations.

The plane of section of CT means that main trunk MCA occlusions are seen as a linear hyperdensity in the sylvian fissure, while internal carotid artery (ICA) or branch MCA occlusions may be seen as hyperdense “dots” in cross section. 2009-11-11 · Brain biopsy in such a patient revealed gliosis with multiple gemistocytes, which, according to the author, is enough to explain the shortened T1 relaxation time . There was also a theory that this is not the bleeding but a short-lasting ischaemia that leads to such an MRI image [ 8 , 9 ]. Hyperdensity in the basal ganglia contralateral to the hemichorea on her head CT is consistent with what has been reported in the literature.
