| Dx acoustic neuroma? | CT w/contrast, MRI of brain |
| TX for acoustic neuroma? | Surgery (go in behind ear and in skull to remove) --Is slow-growing..so not URGENT |

| When would you think of adenocarcinoma of ethmoid sinus? | Initially think is sinus infex..if not responding to abx -- do XR series, CT |
| What is the rare CA that can be found in the mid-20s and is in the roof of the nose, is slow-growing? | Esthesioneuroblastoma |
