Q: My ultrasound showed a white spot on my unborn child's liver. What could it be? How could it affect my child or me?

A:The white spot in the fetal liver refers to calcium deposition. This follows a fetal infection by one of several infectious agents such as cytomegalovirus, toxoplasma, rubella etc. This has no impact on the physical health of the mother. For the fetus, it could have a variable effect depending on the degree of fetal infection. The ultrasound scan by itself is not conclusive to guide further management. That decision has to be based on serial ultrasound scans, the result of serial blood tests referred to as TORCH test and on the overall clinical picture.
