Liver lesions are abnormal clumps of cells in your liver, and they are very common. They will be detected in as much as 30% of people over 40 who undergo imaging tests. 1 The majority of liver lesions are benign (not harmful) and don't require treatment. But in some cases, liver lesions are malignant (cancerous) and should be treated.

on delayed imaging, the centripetally-filled tumor nodules remain hypodense to the rest of the liver parenchyma rather than hyperdense like in a hemangioma.

Most cases of liver hemangiomas are discovered during a test or procedure for some other condition. A focal liver lesion located in the posterior part of segment 4 initially suggests focal fatty sparing or focal steatosis. Liver steatosis is common and takes on many forms at imaging. It may be diffuse and is easy to recognize.

It is just a siderotic iron containing hyperdense nodule. The lesion is almost isointense to liver on T1WI and T2WI, but shows more contrast to the liver on a T1W-MPRGRE (gradient-echo). 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. 2020-04-16 2019-06-23 The causes of hypodense liver lesions are many and they could include benign liver cysts that have no symptoms or malignant tumors which are usually associated with certain symptoms. Sometimes a part of the liver tissue may become hypodense as compared to the nearby tissue due to focal fatty changes or due to primary or secondary tumors. 2017-08-22 particularly inapatientwith chronic liver disease (Fig.2).However, hemangiomas are exceedingly rare inpatients with cirrhosis and therefore will rarely present adiagnostic challenge.

Liver hypodensity on a CT scan is a signal of liver cancer and caused by variable factors. It is may caused by hepatic cysts, hemangioma, liver abscess or liver cancer. Liver hypodensity in the right lobe of the liver usually indicates cystic tumor, such as hepatic cysts and hemangioma. Liver hypodensity is sometimes caused by hepatic fat.

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.

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 … In the arterial phase hypervascular tumors will enhance via the hepatic artery, when normal liver parenchyma does not yet enhances, because contrast is not yet in the portal venous system. These hypervascular tumors will be visible as hyperdense lesions in a relatively hypodense liver. In the arterial phase hypervascular tumors will enhance via the hepatic artery, when normal liver parenchyma does not yet enhances, because contrast is not yet in the portal venous system.
