Portland, I found this post on here from a member who had similar CT results as you and I have had(mild asymmetrical swelling in the BOT), though his actually showed a mass and some reactive nodes, whereas mine didn't. He also finally had another biopsy much like the one you are having and his came back as squamous papilloma, which is a benign condition. Perhaps you can ask your ENT about it. Here is the thread
