Susanmt - hi, I haven't posted a message before but have just seen your note about cysts on the brain and wanted to share my experience with you. At 16 weeks, I had a 'positive' downs indictor, resulting from an AFP bloodtest. My chances were something like one in 250 and as the hospital's track record for miscarriage resulting from an Amnio was considerably less than this, I opted to have the test. Imagine my horror when, whilst scanning my child when undertaking the Amnio, they also discovered several cysts on the brain, of varying sizes. I was informed that this was an indication of Edwards system and coupled with my already high AFP rating was taken very seriously by the consultant.
My partner and I were counselled in a very frank manner and I think what they told us was key. Firstly- cysts quite often appear in the brain of unborn children. They are too small to see at a 12 week scan, and quite often by the time they are viewed at a 20 week scan are insignificant enough not to be an issue UNLESS THEY ARE COUPLED WITH ANOTHER GENETIC INDICATOR - in my case, my AFP reading. In other words, if I had had had a normal AFP, and no Amnio test and my cysts had been spotted at 20 weeeks - there would probably not have been so much of a scare.
It would be interesting to know therefore in what context your poor brother found out about these cysts.
To cut a long story short, my amnio came back fine
and I was then in the advantageous position of knowing for sure that my child was OK. In my case I think an amnio was a blessing. However - as the cysts were fairly significant, I was kept under a Consultant for frequent monitoring (my Hospital is a Womans Hospital and does a lot of Research) In retrosepct I think it was more for their benefit than mine to aid research into things, but at the time it took the edge of my pregnancy a bit - like this overhanging fear that something was not quite right. I even had a scan at 36 weeks (they thought I was breech) and even then they were still there, yet tiny. It seems that as the skull grows the cysts decrease.
My DS is now 23 months old and fantastic, no issues at all. Oh - and one last thing, the consultant said in cases where cysts existed for no apparent reason, the only link thay had found between them and anything else, was a high incidence of left-handedness. And guess what!! yes he is!
I am now 9 weeks pregnant again and worrying about which tack to take this time. I am considering going for a nuchal fold and if nothing shows up just leaving it there. On the other hand, an amnio would tell me straight.
Do let me know how your brother gets on - I really do wish you all well.
