Would you treat a brain abscess due to S. anginosus longer than one caused by another organism?

Depending on the Clinical Picture, usually standard duration, but I once had a case with Strep anginosis abscess which started as a liver abscess, went on to be a pneumonia, then a brain abscess and also Thoracic Spine intramedullary abscess. I did 12 weeks of therapy. Repeat scans showed a mild decrease in the size of the brain abscess(<5mm), and my patient clinically improved, so I stopped.
