The maxillary sinus is the most common paranasal sinus involved in NHL.

The paranasal sinus anatomic variations were investigated via coronal section CT scans.

All seven patients with paranasal sinus malignant neoplasms achieved local control.

The lesion primarily affects the nasal cavity, paranasal sinus, and orbit.

Local response correlated with imaging findings of wide paranasal sinus involvement and ostiomeatal complex occlusion.
