Endovaginal color Doppler posterior transaxial scan demonstrates a blood vessel protruding from the spinal canal into the myelomeningocele sac.
(C) Endovaginal posterior longitudinal scan shows the myelomeningocele sac covered by a thick wall (arrowheads). (D) Neonatal picture shows
the focal skin-covered lumbar myelomeningocele. The bluish tinge within the sac is a blood vessel detected by endovaginal color Doppler in B. (E)
