Hello we are from Australia and was wondering if you can please shed some more light on our ultrasound report...we have several appointments with specialists in the coming weeks...but would like another opinon in regards to exactly what it all means? chances of it being down syndrome or similar? chances of death or miscarrage? chances of baby being healthy etc etc? possible treatments? Do we start worrying?

REPORT AS FOLLOWS

Findings: The patient reports current gestation of 20 weeks 3 days, with EDD of 30.06.2008.

A single active fetus was demonstrated. The placenta is sited at the fundus, and appears homogeneous in echotexture, without evidence of haemorrhage. The inferior placental margin is well clear of the os. The amniotic fluid volume is appropriate for gestatiom.
Current biometric detail is as follows:

BPD 51mm (21 5 weeks)
HC 187mm (22 weeks)
AC 176mm (22 weeks)
FL 33.6mm (20 6 weeks)

These are in keeping with the known gestation according to previous ultrasound, to suggest appropriate interval growth.

Two studies were required for complete morphological review. Whilst there was no marked ventriculomegaly, with the ventricles measuring up to 9.9mm, there was a “dangling” configuration of the choroid plexus within the left lateral ventricle. Cranial appearances were otherwise unremarkable, with normal cranial contour and cerebellar/posterior fossa morphology unremarkable. Similarly, normal spinal detail was demonstrated.

In addition, whilst there was no definite hydronephrosis, there was prominence of the renal pelves bilaterally, with associated infundibular prominence. Maximal AP pelvic dimensions of 5.9mm and 4.3mm were demonstrated. The bladder remained distended throughout the course of both studies. Remaining morphological detail was unremarkable, with regular fetal heart trace confirmed.

No previous imaging or results of the first trimester screening study are available for review. There is prominence of the renal pelves bilaterally, with associated infundibular prominence noted. As a solitary finding, this requires repeat imaging for further assessment at 28 weeks gestation. However, in addition to the altered choroid morphology as a further soft marker, raises the question of an underlying chromosomal anomaly. No associated ventriculomegaly, posterior fossa or spinal abnormality is demonstrated.

wow, that's a lot of medical terms, lol.

From my 'expertise' sounds like most things are functioning great. There's something 'suspicious' in the left part of the brain, but other than that, the brain is fine.

S/he MAY have some type of chromosomal disorder, and Downs Syndrome is part of that. They may do another ultrasound at 28wks to check on that.

Heart, spinal cord and brain are functioning normally.

Baby is growing right on schedule.

I hope I helped a little.

dangling choroid plexus

Hi there, I am also from Australia and read your question about the dangling choroid plexus. I had a scan a few days ago and was asked yesterday to see my obstetrician about the resuslts. Mine said, mildly dangling choroid plexus noted.. prominent ventricular system intracanially. I am unbelievably upset and totally confused. I am not sure where in australia you are but I was told about a hosptial in Berwick Melbourne who has a more specialised machine that can look in more detail at the brain of the unborn. My own baby is due on 27 January 2008 and we are going to make plans for a 28 week scan at this hospital. From the limited research that I have done, a dangling choroid plexus along with other symptons, e.g abnormal heart tracings can indicate downs syndrome, but not on its own. i sincerely hope that you and the baby are okay, I know exactly what you are going through, God Bless.

I'd like to know how the rest of her pregnancy turned out...that reads like a fairly standard ultrasound report to me. On ultrasound there are signs which we look for called soft markers or major findings. If there are a great number of soft markers present we get suspicious for chromosomal anomalies (such as downs). Someof these markers include choroid plexus cysts, large nuchal fold, echogenic cardiac focus, fluid in the kidneys, bright bowel, short femur length, and many more. A lot also has to do with maternal age.
Ventriculomegaly - or dangling choroid, causes include chromosomal and genetic defects, intrauterine hemorrhage or infection, but no clear cut etiology. In damo82's case because the ventrical still measured less than 1 cm, it could just be borderline and not actual dangling choroid. Prominent renal pelvises is another soft marker, which they usually follow up with at 28-32 weeks.
The overall incidence of chromosomal defects in fetal ventriculomegaly is about 10%, commonest trisomies 21, 18, 13 and triploidy. The incidence is HIGER with mild to moderate ventriculomegaly than with severe.
A amnio or villus sampling can always be done as well to check for abnormalities, and genetric couseling made available. 12LRJJ9 i'll keep my fingers crossed for you. Best of luck

Feel free to pm me.

plexus Choroid

I went to see a doctor who specialises in fetal anatomy and sonography. A measurement of up to 9.9 is considered normal, my own came out at 9.2 and the brain had no abnormalities. The rest of the baby was normal too and no further scans are required. It was a big relief!! Damo82 let us know how you get on, I am praying for you
