The influence of a dropping sigma-meson mass on previously calculated in-medium pion-pion correlations in the J=I=0 (sigma-meson) channel is investigated. It is found that the invariant-mass distribution around the vacuum threshold experiences a further strong enhancement over and above the standard many-body effects. The relevance of this result for the theoretical interpretation of this result for the theoretical interpretation of recent A(pi-2 pi)X data is pointed out.
