Cirrhosis is a permanently scarred and damaged liver. The The scan planes are directed between adjacent ribs. Liver Ultrasound - Lobulated Hypoechoic Lesion. Whereas the longitudinal liver sonography is done in parallel planes, subcostal scans are swept through the liver in a fan-shaped pattern. A liver transplant replaces the damaged liver with a healthy one from a donor. It is almost always accompanied by a considerable diminution of size; the granulations and the atrophy generally commence at the edges, and the latter attains its extreme development at this point; the edges consequently appear very much thinned, and at last form a mere seam, consisting of cellulo-fibrous tissue, which is contained between two condensed laminae of peritoneum, and reflected over the convexity, or inverted into the concavity of the liver. Now scan down the left border by angling the transducer. Outside links: For the convenience of our users, RadiologyInfo.org provides links to relevant websites. 4.4b, c).

Solitary hepatic cysts, usually congenital, are found in up to 4% of the adult population. The heart rests upon the diaphragm in this area. In the same manner as the granulations may produce a racemose appearance of the hepatic surface, they may, when several of them are grouped together, produce larger protuberances, or lobes; if the interstitial cellular tissue is much condensed, the peripheral groups may become pediculated, so as to resemble mere appendices. 4.17a) to triangular below (Fig. If a person has several risk factors and suspects that they may have liver fibrosis, they should consult a doctor. Cirrhosis of the liver. Fig. 4.28). 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. When the increase of size is the result of congestion, or of temporary hyperaemic turgor, the liver retains the general outline of its normal condition: but if this affection becomes permanent, the vertical diameter soon predominates considerably.

The left lobe is easier to visualize because it is being scanned through the epigastrium and because the left hemidiaphragm is lower than the right (Fig. This evaluation was performed on axial fat-suppressed T2-weighted images combined with coronal T2-weighted images. Left untreated, liver fibrosis can eventually lead to cirrhosis of the liver which is not reversible. 2The liver cannot be scanned by the shortest route, but only from beneath the costal arch or between the ribs (Fig. Healthcare providers can use several scales to define the stages of fibrosis. You should get to know the liver in three dimensions. This scan corresponds to the section in Fig. 4.25). Federal government websites often end in .gov or .mil. The Ishak fibrosis scoring system is more complex, and it typically runs from 0 to 6: Using the Ishak scale, the most advanced stage of fibrosis a person can have before developing cirrhosis is stage 5. Extensive metastatic deposits can create a very nonhomogeneous pattern that involves the entire liver and may be difficult to interpret (Fig. Many findings can be adequately interpreted based on their ultrasound features, whereas others will require additional studies. These and similar scoring systems take into account the effect that the fibrosis has had on the portal vein, which delivers blood from the intestines to the liver.
