purulent means producing or containing pus. Pyogenic means pus forming, which I think is the same as pus producing. Suppurative is another one, it means containing or producing pus. I think what your looking for is purulent.mpyema means the collection of pus within a body cavity but when you are talking about the pleural cavity it is another word, pyothorax. Pyothorax is the correct term to use … when you are talking about the accumulation of pus in the pleural cavity.
