T2 weighted image allows to differentiate between the tumor, displayed as a low signal intensity area extensing into the nasal cavity and left maxillary sinus, and the acute inflammatory tissue, which shows up bright. Long standing inflammatory changes may also result in thickened, dessicated mucus, with low signal intensity. The presence of inflammatory tissue in the ethmoid is important since it excludes the need for a neurosurgical approach.
