Figure 11 (A-F): Axial T2 (A) and T1WI (B) reveal heterogeneous mass lesion in left maxillary sinus, left nasal cavity, PPF, and masticator space in a proven case of adenoid cystic carcinoma of left maxillary sinus. Coronal T2WI (C) reveals extension of T2 hypointense mass in the left cavernous sinus. Postcontrast coronal image (D) reveals homogeneous enhancement of mass with perineural spread along maxillary nerve in foramen rotundum (thick arrow) and vidian nerve in vidian canal (thin arrow). Dural invasion is seen in postcontrast coronal image (E). Axial CT bone window (F) reveals bone destruction
