An infant displays failure to reach developmental milestones. There is a prominent 2 cm lumbar meningomyelocele. An MRI scan of the brain demonstrates downward extension of the cerebellar vermis and displacement of the medulla from a small posterior fossa into the foramen magnum. There is tenting of the tectum of the midbrain. The cerebral ventricles are enlarged. The spinal cord has findings of hydromyelia. Which of the following conditions is most likely to account for these findings:

A Dandy-Walker malformation

B Viral meningoencephalitis

C Arnold-Chiari malformation

D Maternal folate deficiency

E Werdnig-Hoffman disease

Sounds like Arnold-Chiari, but tenting is predominant in Dandy-Walker,yes? Could you explain how the hydromyelia happens? Thanks!
