Can an arachnoid cyst or a chiari 1 malformation grow?

Sometimes: Aarachnoid cysts can show enlargement with age. Chiari malformations can worsen via increased cord compression or by hydrocephalus/syringomyelia.

Yes: Chiari 1 is not likely to grow, though symptoms can occasionally become worse. Arachnoid cyst is an entirely different condition and they can grow.
