The “Lasso Sign” : An Early Sonographic Sign of Posterior Meningocele

الملخص EN

Posterior meningocele is an uncommon form of spina bifida.

We present a case of unique posterior meningocele diagnosed at the early second trimester anatomical scan using 2D and 3D ultrasound.

The sonographic appearance resembled “lasso”.

The prenatal follow-up was uneventful, with no demonstration of tethered cord.

Clinical, neurological and radiological examinations following delivery and at the age of four months were unremarkable.
