Anatomical terms of microanatomy. The lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic (histological) scale. The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein. The angle between the anterior and posterior surfaces of the liver is broadened (). As a result of this, fibrosis can reduce overall liver function and impair the organs ability to regenerate.

The Metavir scoring system rates the progression of fibrosis on a scale from A0 to A3: The Metavir system also scores the level of fibrosis from F0 to F3: Cirrhosis is scar tissue building up in the liver. The edge of all the leaves would be lobulated. I have this unexplained pain on my right side. The third form and highest degree, which bears most resemblance to congenital lobulation, results from the obliteration of one or more branches of the vena portas, from inflammation and the consequent shrivelling and atrophy of the hepatic sections supplied by their ramifications.

The scans proceed from left to right, following the costal margins. "No free fluid" is also good news. The section of the liver has a trapezoidal shape at this level. Mentally picture the liver lying beneath the ribs, and angle the scan upward. The majority of hemangiomas with type-3 enhancement show lobulated margins. The latter are of peculiar interest, as the nature of the hepatic malformation, taken in connection with the increase or diminution of size, is characteristic of the internal affection of the viscus. Scientists are also looking for better ways to treat certain causes of liver fibrosis, such as alcohol use or NASH. This can starve and eventually kill healthy liver cells, creating more scar tissue in the process.
