Imaging spectrum of spinal dysraphism on magnetic resonance: A pictorial review

Figure 13 Posterior meningocele with persistent terminal ventricle. T2 weighted sagittal (A) and axial (B) images of lumbosacral spine showing posterior meningocele and persistent terminal ventricle. There is herniation of a CSF filled sac (arrowhead) through a posterior spina bifida (dashed arrow) consistent with posterior meningocele. No neural tissue is noted within the CSF sac. There is another CSF attenuation lesion in conus medullaris (black arrow) suggestive of persistent terminal ventricle. The filum terminale is short and thick (white arrow) with low lying spinal cord suggestive of tight filum terminale. CSF: Cerebrospinal fluid.
