Figure 8. (a) Sagittal spinal ultrasound (SUS) showing anechoic myelomeningocele in continuity with both a tethered cord (the conus lies at L5) and a cutaneous soft tissue mass. (b) Axial SUS (same patient) showing anechoic myelomeningocele in continuity with tethered cord. (c) Sagittal line diagram showing features of a myelomeningocele. Note the large dysraphic defect in the neural arches, the herniated sac of exposed neural tissue posteriorly (arrows) and cerebrospinal fluid (CSF) anteriorly.
