Fetal liver calcifications (FLCs) are isolated or multiple areas of increased echogenicity in the fetal liver, with an estimated prevalence of 5-10 per 10 000 births. However, their clinical importance remains still unclear. Although they are often linked to infections, chromosomal disorders, thrombotic events, or tumors, isolated FLCs generally have a favorable outcome. This article aims to present a case of a 29-year-old pregnant woman with a low-risk cfDNA test, who presented for the first trimester screening scan at our hospital at 12 weeks of pregnancy. The morphology scan at 20 weeks and 5 days revealed a normal fetal size with areas of increased echogenicity in the liver. No other fetal issues were identified. The patient was monitored throughout her pregnancy at our center, receiving genetic counseling and tests for detecting cystic fibrosis, STORCH (syphilis, cytomegalovirus, herpes virus 1;2, rubella, and toxoplasma), fetal echocardiography, and MRI, all of which were normal. At 35 weeks and 6 days, the patient gave birth to a healthy male, and all subsequent postnatal examinations confirmed the baby's health. This article aims to offer comprehensive insights into the management and postnatal outcomes of isolated FLCs, based on a review of the literature.
