The patient presented with inflamed infraorbital and cheek region for about 3 weeks, no prior history of malignancy. Diagnosed squamous cell carcinoma of the maxillary sinus with orbital and ethmoidal extension. Bone window axial computed tomography scans (A, B, C, D) show direct tumor invasion of pterygopalatine fossa and sphenopalatine fissure (ellipse), as well as invasion of the inferior orbital fissure and foramen rotundum (rectangle). The tumor also invades the right hard palate with the enlargement of the greater (arrow) and lesser (arrowhead) palatine canals, and the infraorbital canal (triangle), compared to the normal left one. Axial T2-weighted image (E) shows the right PPF, pre- and retroantral fat obliteration (ellipses) versus the normal left side. T1-weighted fat-saturated coronal image (F) with contrast medium demonstrates the contrast enhancement of the right Meckel’s cave (dashed arrow), not seen on CT, suggesting the involvement of the trigeminal ganglion.
