Objective: To present HDlive Flow with spatiotemporal image correlation (STIC) and HDlive Silhouette features of isolated fetal pericardial effusion (IFPE) detected at 17 weeks and 4 days of gestation.
Case description: Two-dimensional sonography showed a sickle-shaped echo-free space (5.6 mm) located along the right-side of the fetal heart (atrioventricular groove) at 17 weeks and 4 days of gestation. Radiant flow revealed no flow inside the cyst. HDlive Flow and HDlive Silhouette clearly depicted the spatial relationship between a tadpole-shaped echo-free space and the fetal heart. The cyst disappeared at 24 weeks and 5 days of gestation. A healthy male neonate was delivered at 40 weeks and 4 days, and had no complications. There was no developmental or neurological disorder of the baby one year after birth.
Conclusion: HDlive Silhouette may provide information on the spatial recognition and origin of an echo-free space of the fetus.
