The Paneitz operator is a fourth order differential
operator which arises in conformal geometry and satisfies a certain covariance property.
Associated to it is a fourth order curvature -- the $Q$-curvature.

We prove the existence of a continuum of conformal radially symmetric
complete metrics in hyperbolic space $\mathbb{H}^n$, $n>4$, all having
the same constant $Q$-curvature.

Moreover, similar results can be shown also for suitable non-constant
prescribed $Q$-curvature functions.
