Image of lymph node v of liver met on MRI

[mpbser]

Here is a question that I know will take me an inordinate amount of time to find an answer to online, so I thought I would throw it out here to the group to see if anyone may have answers:

Does an MRI image of a cancerous lymph node, e.g. periportal or portocaval (aka portacaval), have the same characteristics of cancerous tumors in organs such as the liver?

In other words, since tumors in the liver and colon have distinct characteristics, e.g. rim enhancing with diffusion restriction, on MR imaging, should we also expect to find those same characteristics when a lymph node is a met?

I can’t answer your post but I find it interesting. I hope someone can respond.

I don’t think it will be similar lymph node. Even for liver Mets not all of them present in a standard way. My radiologists thought I had a secondary cholangiocarcinoma based on how it looked in the MRI, but biopsy confirmed it to be CRC. Radiopedia should have more info on presentation of abnormal lymph nodes.
