15 weeks GA !
What is / are the most likely diagnosis / diagnoses?

```
  Cystic hygroma.
```
```
  Encephalocele.
```
```
  Amniotic band syndrome.
```
```
  Holoprosencephaly.
```
```
  Hydranencephaly !
```

I think the skull bones are not well seen , supposed by 15 weeks to be well developed
Amniotic Band Syndrome (ABS) !
Thin aberrant bands of tissue attached to the fetus.

· Fetal deformities.

· Restriction of fetal movement secondary to entrapment by bands.

· Bands may be very difficult to visualize but characteristic fetal deformities in a non-embryonic distribution is highly suggestive !
