Neuroanatomy question

a pediatrician examining an infant found a large swelling in the lower part of the infants back ove the fourth and fifth lumbar vertebra. The summit of the swelling had an oval raw area from which a clear fluid was dicharging. The legs were hyperextended and feet were held in a position of talipes calcaneus.

What is the problem?

[I think it may be spina bifida meningocele, since there is not mention of spinal cord in the swelling. however i am not sure and i don't know why the swelling would have  a discarge (CSF).]

Explain all aspects of the defect on the back.

[ lack of folate and possible the LE issues are residual due to residual paralysis]

Can anyone help me??
