Is this a nodular subcortical heterotopia- neonatal brain ultrasound

This neonate shows a large (3.5 cms.) sized lesion in the Rt. cerebral hemisphere. What do these neonatal brain ultrasound images portray? Is it a case of neonatal nodular subcortical heterotopia or is it an ICSOL due to intracerebral bleed or some form of glioma?
the answer: this is a large  intracerebral  haematoma occupying the right parietal and occipital regions of the  neonate's  brain. This was the diagnosis based on the MRI scan.

Multiple fetal anomalies- in 3rd trimester

This 35 week fetus has multiple anomalies.
Short femur, 2 vessel cord, prominent fetal labia....
and also a potential cardiac anomaly.
Fetal abdomen and AC:

Fetal head and BPD:

2 vessel cord- single umbilical artery:

Fetal labia:

Fetal femur and FL:

Fetal heart- 3 vessel view:

Video of fetal echo: is there a mild hypoplasia of the fetal left heart?

Fetal abdominal cystic mass- dermoid cyst

This 34 week old fetus shows this large cystic lesion with an echogenic nodule within it. The cyst measures 4.5 cms. whilst the the solid nodule was 2.5 cms. in size.

Some 3D and 4D ultrasound images of 3rd trimester fetal face

This was a 34 week old fetus. Managed to capture a few 3D ultrasound images using the GE- P5 pro. It was a cephalic presentation. So had to rotate the image on the sonography machine.

And managed to catch the fetal leg and the foot too:

Severe left internal carotid artery stenosis:

This patient has the right hemiplegia following a cerebrovascular accident involving the left parietal lobe. Color Doppler imaging of the carotid tree shows severe stenosis, 80 to 90%, involving the left internal carotid artery close to its origin from the common carotid artery.
The colour Doppler image below shows the internal diameter of the left internal carotid artery is less than 3 mm near its origin. This is definitely abnormal and shows severe stenosis.

spectral Doppler trace of the left common carotid artery appears relatively normal.

however, the left internal carotid artery shows a definite evidence of severe stenosis with peak systolic velocity reaching up to 224 cm/s suggesting greater than 90% stenosis at this level. The normal peak velocity of flow at the internal carotid artery should be less than an and 120 cm/s.

the video below shows the characteristic spectral waveform seen in this case. The characteristic high pitch sound of the Doppler waveform and high velocity flow at the site of left internal carotid artery stenosis can be appreciated.
