Axial MRI images of a 66-year-old female patient with right maxillary sinus squamous cell carcinoma (SCC). She presented with symptoms of chronic rhinosinusitis for which a CT sinuses was performed (not shown) demonstrating unilateral maxillary sinus disease, suspicious for malignancy. Axial T2 weighted image (a) exhibits an isointense soft tissue lesion (white arrowhead) permeating and extending through the right maxillary sinus, which can be differentiated from the high T2 signal normal mucosa (arrow). Both the SCC (white arrowhead) and normal mucosa (arrow) are hypointense on T1W imaging (b). On T1W post-contrast imaging (c), the lesion demonstrates less enhancement (white arrowhead) compared to the adjacent hyperenhancing sinonasal mucosa (arrow) (c). Transpatial spread into the right pterygopalatine fossa is also identifiable on all sequences (black arrowheads with white outline)
