In the framework of the standard cubic-quintic nonlinear Schrodinger model in a three-dimensional (3D) dispersive medium, one-parameter families of spatiotemporal spinning bright solitons were obtained. The solitons are in the form of a doughnut and are subject to an instability against azimuthal perturbations.
