Real time B mode sonography of pelvis showed gravid uterus with single gestation with variable presentation. FETAL BIOMETRY: 47.6mm 20 wks 3 days Tic 178.5mm 20 wks 2 days AC 156.8mm 20 wks 6 days FL 33.0mm 20 wks 2 days 20 wks 0 day 30.2mm PLACENTA- Position Anterior, upper ut. segment LIQUOR adequate Cardiac activity :152BPM EF body weight 364.0 gms. Expected EDD 28-01-2018 27-04-2017 Mean gestational age 20 wks 3 days. Gestational age by LMP 19 wks 6 days. ANATOMICAL SURVEY FETAL BRAIN AND FACE -No evidence of ventriculomegaly. A cleft is seen between the cerebellar hemispheres, it communicate with fourth ventricle. Adv 3D/4D scan to see for sagitial images of vermis for confirmation. Fetus is in persistent cephalic position with head deep in pelvis and fetal facial profile could not be properly seen outlined by liquor. Adv-3D/4D scan of face. 101

### output:

Hi, As per the sonogram report mentioned, the findings are normal and almost corresponding to the estimated pregnancy age.  There are no obvious fetal anomalies. The lie of the fetus is not of much significance at this stage since the fetus is small as compared to the liquor and hence, the position keeps changing. However, as the fetal head seems to be deep within the pelvic cavity, further imaging is necessary to see details.  Hope I have answered your query. Let me know if I can assist you further.
