OBJECTIVES INTRACYSTIC HEMORRHAGE
CASE REPORT INTRACYSTIC HEMORRHAGE
presented at our institution at 23 weeks of gestation for a routinely obstetrical ultra-sound examination.

DISCUSSION INTRACYSTIC HEMORRHAGE
Placenta INTRACYSTIC HEMORRHAGEavillousspaces or “placental lakes” :
They are located mainly within the placental tissue and are characterized by a turbulent blood flow on real-time ultrasonography.
They result from bleeding that is maternal in origin. On ultrasonography, they appear as a hypoechoic area between the chorion and the uterine wall.
CONCLUSION INTRACYSTIC HEMORRHAGE
Most INTRACYSTIC HEMORRHAGEsubchorionic cysts are thought to be obstetrically harmless.
However, a large subchorionic cyst near the placental cord insertion site should be considered a pathological lesion and followed closely by US examination, to rule out a secondary intracystic hemorrhage, a partial occlusion of umbilical cord blood flow, a fetal growth restriction secondary to the cyst or an intraamniotic rupture leading to fetal death.
