ABSTRACT

The finding of increased echogenicity in the fetal abdomen is common. This may be in the fetal bowel, kidneys, or in the liver. Discrete isolated / single echogenic foci in the fetal abdomen are a relatively common finding at the routine anomaly scan. A thorough search should be made not only for other such foci in the brain, and chest but also for any other markers for chromosomal or infective signs in the fetus. Typically, congenital infections such as varicella present with multiple foci in the liver and with additional features such as growth restriction, and ventriculomegaly. Screening for evidence of maternal infection can be considered for reassurance. If screening is negative, then a follow-up growth scan would identify any further developments such as an increase in the size of the foci, with significant vascularity suggesting a vascular malformation.
