Katie - Try not to worry! Lily had this. They found an ecogenic focus in the left ventrical at 19 weeks. She also had a 2 vessel cord, so the risk for downs was a bit high, 1:500 and i was only 18. I had a specialist scan at 21 weeks. Even before the scan, she said it shouldn't be a problem and they are probably just covering their backs. After she said i didn't need an amnio but could have had one if i wanted, i didn't. The adjusted risk was 1:3000 which at the age of 18 is pretty high, but not high enough to be that much of a problem. As you know, she is perfectly healthy. They can also mistake this for a calcium depost, as they look alike.
