Here is a macro that creates the intersection of two ROI Manager  
selections. It requires ImageJ 1.37j, which adds the  
Edit>Selection>Create Selection command.

   requires("1.37j");
   orig = getImageID();
   setBatchMode(true);
   if (roiManager("Count")!=2)
       exit("Two ROIs in ROI Manager required");
   roiManager("Select", 0);
   run("Create Mask");
   rename("Mask1");
   mask1 = getImageID();
   roiManager("Select", 1);
   run("Create Mask");
   mask2 = getImageID();
   imageCalculator("AND", mask2, mask1);
   run("Create Selection");
   roiManager("Add");
   selectImage(orig);
   roiManager("Select", 2);
   roiManager("Rename", "Intersection");
