Our ultrasound examination found a midline soft mass behind the cervical spine, with an anechoic center. There was no obvious cleft. The fetal brain was normal, without Arnold Chiari syndrome nor hydrocephaly. The prenatal MRI additionally found a "tethered" cord around C3-C4 levels.
Our hypothesis was a cervical meningocele with filiform connection, without any significant consequence on the spinal cord or the brain. A similar case was described by Dr Cuillier [1]. We followed the pregnancy and the baby was delivered normally.
The diagnosis was confirmed at surgery: cervical meningocele, without significant spinal cord involvement except for a few rootlets. There were no complications on follow-up after surgical excision.
