Using the effective Lagrangian method, we analyze the electroweak corrections to the anomalous dipole moments of leptons from some special two-loop topological diagrams which are composed of neutralino-slepton (chargino-sneutrino) in the minimal supersymmetric extension of the standard model (MSSM). Considering the translational invariance of the inner loop momenta and the electromagnetic gauge invariance, we get all dimension six operators and derive their coefficients. After applying equations of motion to the external leptons, the anomalous dipole moments of leptons are obtained. The numerical results imply that there is a parameter space where the two-loop supersymmetric corrections to the muon anomalous dipole moments may be significant.
