Fig. 1

Sinus mucormycosis with extension to orbit and neck. Coronal T1-weighted (A) and axial T2-weighted fat-saturated (B, C) images show T1 hypointense and T2 hyperintense soft tissue (black arrows) in the right maxillary sinus extending posteriorly into retromaxillary neck space (curved white arrow). Contrast-enhanced axial T1-weighted fat-saturated image shows peripheral enhancement with central non-enhancing area (straight white arrows). Note the intraconal fat stranding in the image (A) suggesting orbital involvement (white arrowhead)
