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

Figure 8 Cervico-dorsal myelomeningocele with Chiari II malformation. T2 weighted sagittal (A), T1 weighted sagittal (B) and T2 weighted axial (C) images of cervicodorsal spine showing myelomeningocele. There is posterior herniation of a CSF filled sac (dashed arrows) containing nerve fibers (black arrow). Spinal cord show kinking at the same level and dilated central canal (white arrow) suggestive of syringohydromyelia. There is no overlying skin cover. Sagittal T1 weighted (D) and axial T2 weighted (E and F) images of brain shows herniation of cerebellar tonsils (black arrow) with tectal beaking (white arrow). Fourth ventricle is elongated and tubular shaped. There is colpocephaly suggestive of corpus callosal agenesis (in E) and interdigitating gyri (dashed arrow in F) suggestive of fenestrated falx.
