Location of lesion

[njtopa77]

I have a 6cm lesion located on imaging tests which is indeterminate and being biopsied. I'm confused because on two of the tests (CT and US) it says the lesion is in the medial aspect of the right lobe whereas on the MRI it says it's in the junction of the left and right lobes. Can these both be right? Can someone explain to me what medial aspect of right lobe means? Thanks in advance.

Great to know it's not malignant! And as you already noted, you know the cause as well given your birthcontrol history. Hopefully the surgery will require minumal resections and be done laproscopically.

I just got my definite diagnosis - atypical adenoma - needs to come out but so far the biopsied piece is benign.

Thank you so much for answering. I'm still waiting on the biopsy results but they did a percutaneous biopsy (I don't know if that was a core). So far my differential diagnosis has not pointed one way or the other. My US dd was three indeterminate lesions of benign or malignant etiologies. My MRI dd was five indeterminate lesions with the 6cm lesion being dominant (the other 4 are <1cm) favoring a neoplastic process benign or malignant which would be atypical of FNH or adenoma. More aggressive neoplasm favored. Of the four additional lesions,1 was a definite, 1 was a likely (both those referred to as subtle) and two were a maybe (from the body of report). I don't know if that means I have 2, 3,or 5 lesions. As an aside, I did take oral contraceptives for 16 years so I am hoping this is just an atypical benign.

The anterior right lobe does touch the side of the medial left lobe. So it sounds like the lesion is situated just between the left segment-1 and -4, and right segment-5 and -8. This is a common location given the amount of vascular/biliary activity in the region.

Have they told you what the differential diagnosis is so far? I've had many liver biopsies myself for tumors. Hopefully they will be able to get a clean, adequate sample. Make sure that they use "core" needles if possible, vs aspirated needles. The core approach will provide a better sample for the pathologists to work with. Nothing worse than having them going in and still end up indeterminate due to insufficient biopsy material.

Hope all goes well and the results are benign.
