The inclusive A(gamma, pi(+) pi(-))X reaction is studied theoretically. A sizable enhancement of the cross section is found, in comparison with the scaling of the deuteron cross section (sigma(d)A/2). This enhancement is due to the modifications in the nuclear medium of the N-gamma --> pi pi N amplitude and the pion dispersion relation. The enhancement is found to be bigger than the one already observed in the (pi, pi pi) reaction in nuclei.
