## Abstract

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.
