What is hepatic capsular?

Hepatic capsular retraction is defined as loss of the normal convex hepatic contour, an area of focal flattening or concavity.

What is capsular enhancement?

Capsular enhancement on early- phase images may reflect increased blood flow at the inflamed liver capsule, whereas enhancement on delayed images may reflect the early events of capsular fibrosis (7,8).

What is confluent fibrosis?

Confluent hepatic fibrosis is a cause of wedge-shaped or concave-marginated abnormalities in the cirrhotic liver: it occurs more frequently in the medial and anterior segments of the liver and tends to extend from the hilum to the periphery.

Is the liver encapsulated?

The liver is made of very soft, pinkish-brown tissues encapsulated by a connective tissue capsule. This capsule is further covered and reinforced by the peritoneum of the abdominal cavity, which protects the liver and holds it in place within the abdomen.

Why do I have cysts in my liver?

The cause of most liver cysts is unknown. Liver cysts can be present at birth or can develop at a later time. They usually grow slowly and are not detected until adulthood. Some cysts are caused by a parasite, echinococcus that is found in sheep in different parts of the world.

What is liver parenchyma?

The liver parenchyma is mostly comprised by liver cells (hepatocytes). The major supporting cells are Kupffer cells and stellate cells. Kupffer cells are the resident mononuclear phagocytes. In quiescent state, the stellate cells are responsible for vitamin A storage and metabolism.

Can CT scan detect liver fibrosis?

CT scans can be used to screen for liver fibrosis and justify the use of more accurate diagnostic methods such as first-line serologic testing and the well-established and easily performed Fibroscan.

What is confluent fibrosis liver?

Focal confluent fibrosis was defined as a peri- pheral, wedge-shaped area showing isoattenu ation or hypoattenuation compared with the adjacent liver parenchyma on unenhanced images that was associated with focal flattening or concavity of the normal convex hepatic contour.

How do I know if my liver tumor is benign?

Noncancerous (benign) tumors are quite common and usually do not produce symptoms. Often, they are not diagnosed until an ultrasound, computed tomography scan, or magnetic resonance imaging scan is performed.

What is hyperechoic lesion in liver?

A hyperechoic liver lesion on ultrasound can arise from a number of entities, both benign and malignant. A benign hepatic hemangioma is the most common entity encountered, but in patients with atypical findings or risk for malignancy, other entities must be considered.

What can CTCT tell us about capsular fibrosis of the liver?

CT has been reported to demonstrate intense capsular enhancement along the anterior surface of the liver (, Fig 2, ). Capsular enhancement on early-phase images may reflect increased blood flow at the inflamed liver capsule, whereas enhancement on delayed images may reflect the early events of capsular fibrosis (, 7,, 8 ).

What is confluent hepatic fibrosis on CT scan?

Portal venous phase coronal reformatted CT image shows a fatty mass with peripheral calcification (arrow) at the posterior notch of the liver. Confluent Hepatic Fibrosis. Fibrosis can occur diffusely or focally in the setting of cirrhosis. Focal confluent fibrosis appears wedge shaped at the subcapsular portion and radiates from the hepatic portal.

What is hepatic capsular retraction in cirrhosis?

Hepatic capsular retraction is an uncommon finding that is defined as loss of the normal liver contour due to focal flattening/irregularity or concavity. It is related to several benign and malignant pathologies. The list of differential diagnoses associated with hepatic capsular retraction are given below: 1.

What are the pathologic conditions of hepatic capsular and subcapsular cirrhosis?

Pathologic conditions can affect the hepatic capsular and subcapsular regions by way of peritoneal, hematogenous, biliary, and perihepatic ligamentous routes. Pseudolesions or benign conditions may also be identified on the basis of altered hemodynamics of the liver. Computed tomography and magnetic resonance imaging with a
