A set of equations for MHD vortices is derived, in which the resistivity, the viscosity, the velocity and magnetic field shears, and the density inhomogeneity in the magnetospheric boundary layer are included self-consistently. When only the density inhomogeneity and magnetic shear are taken into account, this set of equations is reduced to an equation similar to the famous Hasegawa-Mima equation. In this case, a dipole vortex solution is obtained, with its parameters determined by the magnetospheric boundary layer conditions. This shows that a stable irregularity with two density perturbations w>0 and w<0 distributed closely may exist in the boundary layer. It is called a dipole vortex irregularity here, some characteristics of it are analytically determined.
