“…The twin peak sign, visible in the late fi rst and early second trimester, is a The placental and fetal membranes (chorion and amnion, respectively) are separate early in gestation, accounting for the appearance of the amniotic sac. After approximately 14 weeks gestation, these membranes fuse and are no longer separately distinguishable (12). In rare cases, chorioamniotic separation can occur later in gestation.…”

The placenta is often overlooked in the routine evaluation of a normal gestation, receiving attention only when an abnormality is detected. Although uncommon, abnormalities of the placenta are important to recognize owing to the potential for maternal and fetal morbidity and mortality. Pathologic conditions of the placenta include placental causes of hemorrhage, gestational trophoblastic disease, retained products of conception, nontrophoblastic placental tumors, metastases, and cystic lesions. Sonography remains the imaging modality of choice for evaluation of the placenta. Magnetic resonance (MR) imaging can be of added diagnostic value when further characterization is required, particularly in the setting of invasive placental processes such as placenta accreta and gestational trophoblastic disease. Computed tomography (CT) has a limited role in the evaluation of placental disease owing to limited tissue characterization, compared with that of MR imaging, and the radiation risk to the fetus; this risk often outweighs the benefit. The primary role for CT is in the evaluation of trauma and gestational trophoblastic disease, for which it allows characterization of the primary lesion and distant metastases.

“…In 2003, we reported in this journal a case of amniocentesis complicated by complete CAS followed by total amnion disruption and the appearance of the fetus in the chorionic cavity. 1 In contrast, the case reported here shows a local amniotic defect, which was posteriorly adjacent to the placental insertion of the umbilical cord (Figure 14). The manner by which an anterior uterine wall puncture could leave the anterior amniotic area undamaged but injure the amnion in the opposite wall is unclear.…”

Separation between amniotic and chorionic membranes is a normal sonographic finding before 14th weeks of gestation. As pregnancy progresses, these membranes fuse and chorionic cavity becomes obliterated. Chorioamniotic membrane separation may occur spontaneously or as a complication of invasive intrauterine procedures. Following invasive fetal intervention, resulting in a condition referred to as chorioamniotic membrane separation (CMS) and it is reported to be associated with adverse perinatal fetal outcomes. Here we present a case of CMS that had occurred after a second trimester amniocentesis and resulted with the delivery of a term healthy baby. Complete post-interventional CMS may complicate pregnancy progression. Although there are no established guidelines to follow, close followup may CMS can be managed to be a morbid, rather than mortal condition.
