A case of prenatally diagnosed limited dorsal myeloschisis with good prognosis.

Diagnosis of fetal spinal dysraphism is a challenge. It is difficult to distinguish between a meningocele, myelomeningocele, and a recently described entity called limited dorsal myeloschisis (LDM). Although myelomeningocele is associated with a poor prognosis, LDM can have a good outcome. We present a case of prenatally diagnosed LDM. Because sonographic examination revealed a round, cystic, septated cervical mass without associated cerebral anomalies, the lesion was initially considered an isolated meningocele. Fetal MRI contributed to correct the diagnosis. A diagnostic error can lead to the wrong surgical support or even the termination of pregnancy. Therefore, we highlight the importance of fetal MRI in such cases, particularly when no cerebral abnormalities are observed on sonographic examination.

Pseudoamniotic Band Syndrome After Fetoscopic Laser Ablation of Placental Anastomoses for Twin-Twin Transfusion Syndrome: Two Case Reports and Systematic Review.

Pseudoamniotic band syndrome is a rare complication that occurs after invasive procedures for complicated monochorionic twins. We report 2 cases of intrauterine recipient fetal death after laser therapy for twin-twin transfusion syndrome due to umbilical cord constriction by the amniotic band.
