the left femoral vein- colour Doppler study

this elderly male patient had redness and mild swelling of the skin over the middle third of the left leg.
This is what we found when we did the colour Doppler study of the left lower limb.
This patient did not have any major pain or tenderness in the thigh.Clinically, he did not have features of deep vein thrombosis. Would you think of this possibility from these Doppler ultrasound images?


The answer: this is a case of Left femoral vein thrombosis. There is near total absence of flow signal in a major part of the left femoral vein. The lack of symptoms is explained by the patient having had anticoagulant treatment for a few days.

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.

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:
