It depends: A hypodensity on a CT an area where the tissue is less dense. These tumors may look hypodense or darker than the surrounding liver. Radiologists can measure the density of these lesions and say whether they are cysts. 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. Queste ultime, di introduzione relativamente recente, coinvolgono solitamente molti organi tra cui le ghiandole salivari. [3][4] while TGF- alone can switch TH2 cells into TH9 cells.
