This paper deals with the following nonlinear equations \[\mathcal{M}_{\lambda,\Lambda}^\pm(D^2 u)+g(u)=0 \qquad \hbox{ in }\mathbb{R}^N,\] where $\mathcal{M}_{\lambda,\Lambda}^\pm$ are the Pucci's extremaloperators, for $N \ge 1$ and under the assumption $g'(0)>0$. We show theexistence of oscillating solutions, namely with an unbounded sequence of zeros.Moreover these solutions are periodic, if $N=1$, while they are radialsymmetric and decay to zero at infinity with their derivatives, if $N\ge 2$.
