Amniotic sheet and amniotic band syndrome: pitfalls in distinguishing two cases

Objective: We aimed to present two cases who were found to have amniotic sheet at prenatal in order to highlight the significance of differential diagnosis of amniotic band syndrome and amniotic sheet and to evaluate prenatal diagnosis and fetal outcome of two cases diagnosed with amniotic sheet. Case: Twenty-seven-year-old pregnant woman at 22 weeks of gestation and 35-year-old pregnant woman at 18 weeks of gestation were referred to our clinic with the pre-diagnosis of amniotic band syndrome. Conclusion: It should be remembered that the differential diagnosis of amniotic band syndrome associated with poor obstetric outcomes and severe fetal malformations and amniotic sheet is of great importance, and that the amniotic sheet is benign but may be a predisposing factor for perinatal morbidity and mortality accompanying with some poor prognostic criteria.
