Ballooning degeneration centre-left and centre-right. H&E stain. A Councilman body can also be seen in the upper-right of the section. In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death.
Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...
A CT scan is the best test to look for bleeding in or around your brain. In some hospitals, a perfusion CT scan may be done to see where the blood is flowing and not flowing in your brain. Magnetic resonance imaging (MRI scan): A special MRI technique (diffusion MRI) may show evidence of an ischemic stroke within minutes of symptom onset. In ...
[3] [4] On CT scans, leukoaraiosis appears as hypodense periventricular white-matter lesions. [ 5 ] The term "leukoaraiosis" was coined in 1986 [ 6 ] [ 7 ] by Hachinski , Potter, and Merskey as a descriptive term for rarefaction ("araiosis") of the white matter, showing up as decreased density on CT and increased signal intensity on T2/FLAIR ...
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.
The brain pia mater is reflected from the surface of the brain onto the surface of blood vessels in the subarachnoid space. In the brain, perivascular cuffs are regions of leukocyte aggregation in the perivascular spaces, usually found in patients with viral encephalitis. Perivascular spaces vary in dimension according to the type of blood vessel.
Three main structures are commonly investigated when measuring midline shift. The most important of these is the septum pellucidum, which is a thin and linear layer of tissue located between the right and left ventricles. [7] It is easily found on CT or MRI images due to its unique hypodensity. [7]
Each case was similar to the previous article. There was some atheroma in the internal brain arteries that led to the cerebral softening of the left side of the brain around the left lateral ventricle, thalamus and corpus striatum. There were similar right sided numbness in some patients, coldness of the extremities, and impairments in vision.
