Left: sagittal T1WI shows isointense soft tissue mass in the nasal cavity.
Top right: coronal T1WI demonstrates that this mass lies in the left nasal
cavity and extends superiorly into the ethmoid sinus. The left osteomeatal
complex is obliterated. Note the mucosal thickening in the left maxillary sinus.
Bottom right: This mass lesion is hyperintense on T2WI. The left maxillary
sinus mucosal thickening is more apparent on the T2WI.
T1WI's with gadolinium shows that this mass enhances homogeneously.
The epicenter is near the middle meatus.
