  A new type of long-lived solitary structures for paraxial optics with two
circular polarizations of light in a homogeneous defocusing Kerr medium with an
anomalous group velocity dispersion has been revealed numerically in the
coupled nonlinear Schr\"odinger equations. A found hybrid three-dimensional
soliton is a vortex ring against the background of a plane wave in one of the
components, and the core of the vortex is filled with another component
nonuniformly in azimuth angle. The existence of such quasistationary structures
with a reduced symmetry in a certain parametric region is due to the saturation
of the so-called sausage instability caused by the effective surface tension of
a domain wall between two polarizations.
