ULTRASONIC FEATURES OF INTRAAMNIOTIC UNIDENTIFIED DEBRIS AT 14-16 WEEKS GESTATION

The objective of the study was to define the sonographic features of v arious echogenic materials which have been observed in the amniotic ca vity of pregnancies in the early second trimester. The study populatio n consisted of women who underwent a transvaginal ultrasound scan of p regnancy at 14-16 weeks' gestation. Our experience in 6500 examination s Performed in both low- and high-risk pregnancies is reported; 249 ca ses of intra-amniotic debris were identified in this population. Five different types of echogenic material were observed in the amniotic fl uid: small floating particles, round structures, cystic structures, so lid and semi-solid masses and highly echogenic material which looked l ike calcification. We conclude that intraamniotic echogenic material m ay be observed during early pregnancy. Its origin and clinical signifi cance need further evaluation.
