Diagnosis : Placental chorioangioma
Chorioangioma is a benign vascular malformation that acts as a A-V
shunt, bypassing the normal placental tissue.
Pathologically, small chorioangiomas can be identified in 1% of placentas, but these are
not large enough to be clinically significant. Larger lesions are less common, 1:3500 to
1:20,000 births.
Sonographically, they are usually seen as circumscribed solid or complex masses protruding
from the fetal surface of placenta. Complications include polyhydramnios, preterm labour,
fetal hydrops, IUGR, and fetal demise. |
