Architectural Distortion??

[WONDERING12804]

I had a screening mammo that showed "scattered fibroglandular densities".  Also it showed "an area which I (the radiologist) believe is simulating architectural distortion superiorly in the right MLO view, not seen with certainty on the craniocaudal view".  It was recommended that I have a compression view in the MLO plane and a 90 degree mediolateral view with ultrasound possibly depending on those mammographic findings.  What does all of this mean?  I've done some research and don't like what I'm finding out about architectural distortion.  I have had no prior surgery or trauma to the breast which would be a benign cause for architectural distortion.  Should I be concerned?  Thanks!

Dear wondering12804:  It is not uncommon for an abnormality to show up in a screening mammogram.  In these cases, spot compression is often recommended to further characterize the abnormality.  It could be as simple as some tissue having folded over on itself and with compression will smooth out.  If the abnormality remains, additional evaluation, such as ultrasound, may be recommended to further characterize the abnormality.  Dense breast tissue is very common in young premenopausal women (noting from your profile that you are 41) and can make interpretation more difficult.  Most of these abnormalities turn out to be benign but it is appropriate to follow up to be sure.
