What condition is myelomeningocele strongly associated with?

Myelomeningocele is a severe form of spina bifida, which is a neural tube defect characterized by an improper closure of the neural tube during embryonic development. This condition involves the spinal cord and its protective coverings protruding through an opening in the spine, leading to a host of complications, including associated structural abnormalities in the brain.

One significant condition associated with myelomeningocele is Chiari II malformation. This condition occurs when the cerebellum and brainstem descend into the spinal canal due to the disruption of normal anatomical relationships caused by the spine defect. In patients with myelomeningocele, there is a notable incidence of Chiari II malformation, which can lead to additional neurological symptoms and potential complications.

Other choices may not be as directly tied to myelomeningocele. Spina bifida encompasses myelomeningocele itself, while Dandy Walker malformation and syringomyelia are different conditions that may or may not be related to spinal defects but are not as specifically associated with myelomeningocele in the way that Chiari II malformation is. This understanding helps clarify the strong association between myelomeningocele and Chiari II malformation, emphasizing the importance of monitoring for this condition
