Narrative:

TCASII warning, initiated go around. Callback conversation with reporter revealed the following information: so stated that he never saw the aircraft. The crew reacted solely on the basis of the RA. The aircraft had been on a visual approach, on base leg for runway 25R. There had been no TA. The runway was in sight at the time. When the crew advised tower of the go around, there was at first silence -- then a clearance for the pattern and a return landing. Reporter admits that it may have been a false alarm.
