The image is now dominated by a chaotic pattern of highly contrasting light and dark areas with no discernible shape, caused by the gas and liquid contents of the stomach. Fig. Many scales also measure the extent of fibrosis and the location or number of septa, which are fibrous bands of tissue in the biopsy sample. The posterior surface is slightly concave in its lower portion and becomes slightly convex superiorly (Fig. Lesions with a round or oval shape are always suspicious for metastasis. 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.

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.

Thus the liver is not unfrequently converted into a thick cake with rounded edges, if the inflammation has been uniform, or it may be converted into a globular mass, compressed into a small space by peritoneal investment, which, in consequence of repeated attacks of inflammation, is transformed into a fibrocartilaginous tissue.
