We predict solitary vortices in quasiplanar condensates of dipolar atoms, polarized parallel to the confinement direction, with the effective sign of the dipole-dipole interaction inverted by means of a rapidly rotating field. Energy minima corresponding to vortex solitons with topological charges ℓ=1 and 2 are predicted for moderately strong dipole-dipole interaction, using an axisymmetric Gaussian Ansatz. The stability of the solitons with ℓ=1 is confirmed by full three-dimensional simulations, whereas their counterparts with ℓ=2 are found to be unstable against splitting into a set of four fragments (quadrupole).
