Hyperechoic liver lesions Dr Mark Bolger and Dr Yuranga Weerakkody ◉ et al. 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.

Etiology Diffusely increased attenuation. iron deposition. hemosiderosis. thalassemia; hemochromatosis: one paper suggests investigation for iron overload if unenhanced liver density is >75 HU 9; copper deposition Although the majority of liver metastases are hypodense and enhance less than the surrounding liver, metastases from certain primaries demonstrate an increase in the number of vessels, resulting in a hyperechoic ultrasound appearance, and arterial phase hyperenhancement on CT or MRI which washes out on delayed scan (c.f. hemangioma which does not show wash out).

Liver steatosis is common and takes on many forms at imaging. It may be diffuse and is easy to recognize. A normal liver is the same density as the spleen and will show four lobes all of equal sizes and shapes. Often, a hypodense mass will not show up on a CT scan unless conducted with Contrast, so the patient will be injected with the dye intravenously. In computed tomography (CT) angiogram or some dedicated CT studies of the abdomen, the use of positive enteric contrast should be avoided as its presence could decrease the sensitivity of the test. There are, however, cases of CT scans with unexpected hyperdense intraluminal contents detected due to the use of certain oral or rectal medications.

The enhancement in the arterial phase is lobulated with nonenhancing septation and in the equilibrium phase the lesion is not different from normal liver parenchyma. Notice that the lesion has a small scar. The hyperdense bowel contents may be mistaken as acute hemorrhage in CT angiogram for detection of GI bleeding.

Increased density in the liver in patients treated with amiodarone is often described in the literature as amiodarone hepatotoxicity. However, it is often an incidental finding with no symptoms or signs of liver disease ref. hyperdense relative to the normal liver [41,44-46].

When a liver hemangioma causes signs and symptoms, they may include: Pain in the upper right abdomen Feeling full after eating only a small amount of food Liver hypodensity is a term used by radiologists to describe areas of the liver on CT scans, according to Dr. Tracy A. Berg. It means there are areas of the liver that appear less dense on a CT scan than the surrounding liver tissue.

I just had a CT done with IV contract, following what was thought was a gallbladder attack and subsquent U/S that showed no gallstones, but did show cysts on my liver. "The CT showed at least 20 hypodense lesions within the liver. The dominant lesions are clearly cysts. The largest is situated within segment 6 inferomedially.
