Hepatic hypodensities are areas less dense on CT than the surrounding tissue. Density is how much something weighs per unit volume.
What size liver lesions are concerning?
Recent work indicates that with colorectal liver metastases, careful MRI or CT should detect 95% or more of lesions larger than about 15 mm.
What causes Hypodensities in the liver?
Most liver metastases are hypovascular and as a result are hypodense on CT in comparison with normal liver parenchyma during the portal venous phase (PVP). Colon, lung, breast, and gastric cancers are the most common causes of hypovascular liver metastases.
Is a 1 cm liver lesion big?
Size – Most incidental liver lesions <1 cm are benign, while some small lesions may be difficult to definitively characterize by imaging methods [13,14]. Most lesions ≥1 cm can be diagnosed either by further imaging (eg, MRI tailored for liver lesion evaluation) and/or histology.
Is 1.5 cm liver lesion big?
Are hepatic lesions cancerous?
Liver lesions are abnormal growths that may be noncancerous (benign) or cancerous. Benign lesions occur for a variety of reasons and are typically not cause for concern. Liver cancer is less common but more serious.

What is splenic hypodensity?
The hypodensity may or may not be anything to worry about and can often be caused by a cyst. More than one would indicate different causes. Hypodensities in the spleen may also be indicative of obstruction of the splenic veins. In your case it may be due to a splenic infarct as it is also pain on breathing…
What is hypodense hepatic lesions?
Hypo-dense lesions: Hypodense lesions from infarcts means that there was loss of brain tissue as a result of lack of blood supply to the brain. This may be due to lack of blood flow or obstruction of blood flow to that area of the brain where the lesions are noted on the Head CT. Hope this helps! …Read more.
