It depends on what you want to do with the struct. If
you can get away with treating it as a completely
opaque struct in Pyrex, then all you need is

  cdef extern from "myheader.h":
    struct MyStruct

But if Pyrex code needs to access any of its members, you
will need to provide Pyrex declarations for at least
those members.
