Case report :
A 28-year-old-woman, G2P1, with unknown obstetric risk factors and no relevant medical history underwent a first ultrasound scans at 13 weeks which revealed no anomalies. The nuchal translucency was 1 mm (CRL: 60 mm). The triple test was done (1/10000).
At 24 weeks, a second ultrasound examination revealed a cervical cutaneous posterior anomaly which suggested a possible cervical filiform meningocele (Image 1,2) . Our differential diagnosis was epidermal cyst.
2D sagittal view of the spine confirmed the diagnosis (Image 3-7). A cervical meningocele with a filifirm connection was our final hypothesis.
An amniocentesis was performed. Fetal karyotype and ACE dosage was normal. Although a prenatal cerebral and spine MRI was performed (Image 8), the diagnosis could not be confirmed. At 36 weeks, this cervical meningocele was poorly visible.
At 38 week, a normal delivery happened. Postnatal neurological examination did not revealed any deficit. The skin’s spine was normal, but there was a midline cervical fluid-like mass. (Image 9).
At one month of life, we performed a postnatal MRI (Image 10-11) to confirm our first diagnosis . The baby was operated one week later for his meningocele.
Image 1-7: 2D ultrasound from 24 to 30 weeks of gestation suggested a cervical filiform meningocele .
