Ultrasound images of abnormalities of amniotic fluid:Table of contents:Hyperechoic liqor:Free floating particles in liqor amnii Polyhydramnios:The above ultrasound images show excess amniotic fluid (the largest single pocket measuring 11 cms. approximately). This suggests mild to moderate polyhydramnios. Particulate matter seen in the fluid is due to fetal meconium. Sonography of polyhydramnios was done using a GE, Logiq-3 ultrasound machine.
Hyperechoic amniotic fluid/ Liquor:
Increased echogenicity of Liqor amni:
These ultrasound images reveal markedly echogenic (hyperechoic) amniotic fluid. The fluid shows almost the same echogenicity as the placenta. Such appearances of the liquor amni on sonography are seen due presence of vernix caseosa (commonest cause), blood or meconium in the amniotic fluid. Images courtesy of Dr. Ravi Kadasne, UAE.

Such freely mobile particles in the amniotic fluid are called free floating particles and are commonly seen in the 3rd trimester. Sometimes, particulate debris, when abundant, can be confused with normal umbilical cord floating in the amniotic fluid, on grey scale B-mode ultrasound. However, Color Doppler easily distinguishes between the two (see Doppler images above). Studies show some direct correlation between the size and number of free floating particles and levels of Maternal serum alpha feto-protein (MSAFP). These particles are presumed to be the result of vernix caseosa shed from the fetal skin. However, free floating particles may be visualized on ultrasound imaging even during the 2nd trimester (when vernix is not present). Have a look at the short ultrasound video clips of free floating particles in a 3rd trimester pregnancy at: http://cochinblogs.blogspot.com/2010/01/free-floating-particles-in-amniotic.html More ominously, such debris in the amniotic fluid may be caused due to hemorrhage into the fluid.
