Narrative:

I was working arriving aircraft to runway 8L. A B737 was on a 3 mile left base for runway 8L on a visual approach. The B737 initiated a go-around due to windshear. I climbed aircraft to 3;000 ft and turned to a heading of 360 (normal procedure). I issued an additional turn to a heading of 300 for a downwind back to the airport and was getting ready to transfer communication when I notice a B767 going around on runway 8R and turning to the north inside the B737. I immediately turned the B737 back to a heading of 360 to avoid conflict with the B767. Then the monitor took over and climbed the B737 to 4;000 ft and initiated another turn. The monitor then assumed control of the B767 to bring the aircraft around for another approach. I had no idea I90 was turning the aircraft on runway 8R to the north. Some communication would have been helpful for this event.
