The theory of hadronic light-by-light scattering contributing to the muon anomalous magnetic moment is reviewed. We present a model for the hadronic light-by-light scattering amplitude consistent with the shortdistance constraints from the operator product expansion.

We briefly review the current status of the hadronic light-by-light scattering correction to the muon g -2. Then we present our semi-analytical evaluation of the pion-pole contribution, using a description of the pionphoton-photon transition form factor based on large-Nc and short-distance properti
