USG at 34 weeks says fetal cavum septi pellucidi width is increased. Should I be worried?
Query: Hello doctor, I am 34 weeks pregnant. Until two weeks ago, all the ultrasound reports were normal. The chance of Down's syndrome was 1 in 20000.

Answer: Hello, Welcome to icliniq.com. Cavum septi pellucidi is a structure present normally in the skull and identified in the ultrasound.

Should I be worried about my second-trimester anomaly scan, which is positive for two markers?

Is 4.77 mm nasal bone size normal for a nineteenth-week fetus?
Query: Hi doctor, During my TIFFA USG at 19 weeks and 1 day, the fetal nasal bone measured 0.44 mm. Will the fetal nasal bone develop after few weeks, or it indicates a short nasal bone?

Answer: Hi, Welcome to icliniq.com. The standard thickness of the nasal bone ranges between 1.5 to 2.5 mm. Your fetal nasal bone thickness is less for the gestation period, and the presence of echogenic focus in the left ventricle indicates endocardial cushion defect, which is seen in the case of Down's syn...

Does a hypoplastic nasal bone suggest Down syndrome?
Query: Hi doctor, I am a 29-year-old pregnant woman and went through an anomaly scan. An anomaly scan showed hypoplastic nasal bone in the baby that might lead to Down syndrome.

NT (nuchal translucency)scan and double marker are screening tests that only tell if the baby is at high or low risk for Down syndrome. It does not rule it out completely. Hypoplastic nasal bone (not well-developed nasal bone) is only one ... Read Full »
