Dear Anna,

Thank you for your interest. Since I noticed the first LUQ echogenic focus almost a year ago, I noted the same finding in 3 more patients. The finding is always exactly the same; the focus does not seem to change in size or location. Since the focus appears to produce some degree of shadowing, it is reasonable to postulate that this is something echo-dense. What this focus represents, however, remains a mystery. I am going to try to persuade one of our obstetricians to order an X-ray on at least one of these babies when they are born to see if this focus shows up. If I have any follow-up, I will post it to the forum. My gut feeling is that this is something unremarkable and that it could be commonly visualized if sonographers were aware of it and specifically looked for it. The reason I am saying that is that several weeks after I alerted our sonographers to the presence of this focus on one of my cases, another experienced sonographer found it on a different patient. According to her, she had "never seen this before" in the 20 odd years she had practiced ultrasound. I find it hard to believe it; -it seems more likely that she never noticed it (considering I have seen it 4 times in less than a year).

Many Regards,

Martin Necas.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
