[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 treatment of hepatic encephalopathy depends on the suspected underlying cause (types A, B, or C) and the presence or absence of underlying causes. If encephalopathy develops in acute liver failure (type A), even in a mild form (grade 1–2), it indicates that a liver transplant may be required, and transfer to a specialist centre is advised ...
Chronic liver disease in the clinical context is a disease process of the liver that involves a process of progressive destruction and regeneration of the liver parenchyma leading to fibrosis and cirrhosis. [1] "Chronic liver disease" refers to disease of the liver which lasts over a period of six months.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is a condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
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.
The exact definition of "rapid" is somewhat questionable, and different sub-divisions exist which are based on the time from onset of first hepatic symptoms to onset of encephalopathy. One scheme defines "acute hepatic failure" as the development of encephalopathy within 26 weeks of the onset of any hepatic symptoms.
Transient hepatic attenuation differences (THAD) are areas of enhancement during the arterial phase of contrast CT of the liver. THAD is thought to be a physiological phenomenon resulting from regional variation in the blood supply by the portal vein and/or the hepatic artery .
Feathery degeneration - large cells with pale flocculant cytoplasm (left-bottom and right-top).H&E stain.. In histo pathology, feathery degeneration, formally feathery degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death associated with cholestasis.
