Ichikawa T, Federle MP, Grazioli L, Nalesnik M. | | Title: | Hepatocellular
adenoma: multiphasic CT and histopathologic findings in 25 patients. |
| Source: | Radiology
2000; 214: 861-868 | | Review:
| This
is an earlier article by the same group that wrote the article on focal nodular
hyperplasia that I mentioned last week.
In
this article, they have described characteristic features of hepatic adenomas.
They are usually single, in the right lobe and are isodense to normal liver on
plain, portal venous phase (PVP) and delayed scans. They are mildly hyperattenuating
to liver on arterial phase images and usually enhance homogenously. They are sharply
marginated and smooth. Other features seen less commonly include fat (seen much
more commonly on MRI), hemorrhage, calcification, prominent vessels.
It
should be possible using multi-phasic CT to differentiate between adenoma, FNH,
hepatoma and hypervascular metastases. | |
