Understanding liver cancer is important if you want to develop an effective treatment plan and live a long and healthy life. If you've received a diagnosis, here are some things you need to know about the condition.

A hyperdense liver on non-contrast CT is an 'old chestnut' radiology exam case. Watch out for ancillary features that may point to the diagnosis such as pulmonary fibrosis and pacemaker ( amiodarone ), or increased density in the spleen and pancreas ( secondary hemochromatosis ).

These hypervascular tumors will be visible as hyperdense lesions in a relatively hypodense liver. However when the surrounding liver parenchyma starts to enhance in the portal venous phase, these hypervascular lesion may become obscured. In the portal venous phase hypovascular tumors are detected, when the normal liver parenchyma enhances maximally.

Importantly, large hemangiomas may not enhance centrally on any postcontrast phase because of cystic degeneration, thrombosis, and/or ﬁbrosis [41,44-46]. In the arterial phase, some smaller hemangiomas will uniformly enhance, rather than adhering to the afore- A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver. A liver hemangioma is made up of a tangle of blood vessels. Other terms for a liver hemangioma are hepatic hemangioma and cavernous hemangioma.

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.

In secondary hemochromatosis (e.g.

"The CT showed at least 20 hypodense lesions within the liver.

Likewise, DECT can also help distinguish hyperdense and hyper-vascular lesions in a single contrast-enhanced scan without the need for a separate unenhanced In the portal venous phase and thereafter, FNH becomes isodense; if present, the central scar enhances more gradually, and may appear hyperdense on delayed On triphasic CT, hepatocellular carcinoma (HCC) is characteristically hyperdense compared to the surrounding liver in the arterial phase, iso- or hypo-dense This is a 53 year old caucasian man, with past medical history of tobacco use, COPD, referred to our hematology clinic due to hyper dense liver on CT scan that Tumors are abnormal masses of tissue that form when cells begin to reproduce at an increased rate.

LIVER CIRRHOSIS. Liver cirrhosis is the end stage of chronic liver disease, caused by diffuse fibrosis and regenerating nodules that result from recurrent necrosis of liver cell and degeneration. It is an irreversible form of parenchymal fibrosis. Liver cirrhosis reduces hepatic function. Caused by. alcohol: 60-70%

The hyperdense bowel contents may be mistaken as acute hemorrhage in CT angiogram for detection of GI bleeding. Active GI bleeding, presented as intraluminal extravasation of contrast material, can also be obscured. Hyperdense Liver after a procedure for an implantable cardiac defibrialltor, this woman has a drop in hemoglobin and hematocrit. The CT scan shows an unusual These hypervascular tumors will be visible as hyperdense lesions in a relatively hypodense liver. However when the surrounding liver parenchyma starts to enhance in the portal venous phase, these hypervascular lesion may become obscured.
