Final answer:

Lumbosacral meningomyelocele is a symptom of Chiari II malformation.

Step-by-step explanation:

The association between Chiari II malformation and lumbosacral meningomyelocele is that lumbosacral meningomyelocele is a symptom of Chiari II malformation. Chiari II malformation is a congenital condition in which the cerebellum herniates downward through the foramen magnum, putting pressure on the spinal cord. It is often associated with the development of lumbosacral meningomyelocele, which is a type of spina bifida where the meninges and spinal nerves protrude through an opening in the vertebral column.
