Many findings can be adequately interpreted based on their ultrasound features, whereas others will require additional studies. Circumscribed changes in the liver parenchyma are often challenging for the sonographer. The congenital form of this affection is owing to an arrest of development; the liver is divided into several lobes, and this division may proceed so far as to present several small livers which are only connected with the main organ by peritoneal folds and the vessels enclosed in them. The differential diagnosis of echo-free hepatic lesions is reviewed in Table 4.1. 2012 Nov 21;18(43):6269-76. doi: 10.3748/wjg.v18.i43.6269.

It means that it What Does Coarse Echotexture Of The Liver Mean? The more violent inflammations of the hepatic peritoneal lamina, affect the surface-layer of the liver, and thus induce changes in form, that vary in proportion to the intensity of the inflammation.

Recognize portions of the liver that are difficult to scan. Notice the right angle formed by the anterior and diaphragmatic surfaces of the liver. The echo pattern shows increased density. Note also the conspicuous perirenal fat (). Press the caudal end of the transducer a bit more deeply into the abdominal wall than the cranial end, so that the scan is directed slightly upward. A malformation which we shall have occasion to revert to subsequently (superficial lobulation) results from an intense development of this process in detached spots. The angle between the anterior and posterior surfaces of the Visualization often becomes poor at this point, especially in obese patients and when there is interposed gas in the right colic flexure. Scans may also show rounding of the inferior hepatic border (see p. 46) and narrowing of the hepatic veins (see p. 61). 4.16Scanning across the superior border of the liver.

The majority of hemangiomas with type-3 enhancement show lobulated margins. Doctors refer to the latter condition as metabolic syndrome. 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 costs for specific medical imaging tests, treatments and procedures may vary by geographic region. Fig. Fig. The craniocaudal extent of the right lobe is generally said to be 12 13 cm at the midclavicular line, although the normal liver is quite variable in size.

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. The fatty liver is characterized by increased echogenicity relative to the renal parenchyma (Fig. Hereditary cystic liver disease is characterized by cysts ofvarying size that permeate the liver (Figs. As a result of this, fibrosis can reduce overall liver function and impair the organs ability to regenerate. If a person has several risk factors and suspects that they may have liver fibrosis, they should consult a doctor.
