In this paper we study a nonlinear evolution inclusion of subdifferential
type in Hilbert spaces. The perturbation term is Hausdorff continuous in
the state variable and has closed but not necessarily convex values. Our result
is a stochastic generalization of an existence theorem proved by Kravvaritis and
Papageorgiou in .
