I'm sorry that you are having to go through this problem with regards to your child.
On the basis of the report given it looks like your child at present has a complex congenital neurological condition.
Most of the points mentioned in the MRI
report are known to occur as separate entities in children at birth or in infancy.
While conditions like Hydrocephalus
can be managed well by surgery with good long term results neuronal migration defects are very difficult to treat completely.
Hoping foe the best for you and your child
