The influence of a reduced σ-meson mass on previously calculated in-medium ππ correlations in the J=I=0 (σ-meson) channel is investigated. It is found that the invariant-mass distribution around the vacuum threshold experiences a further strong enhancement with respect to standard many-body effects. The relevance of this result for the explanation of recent A(π,2π)X data is pointed out.
