metastasis to maxillary division and gasserian ganglion
Open biopsy of the left maxillary sinus revealed

left infraorbital canal is enlarged with destruction of the bony boundary (2).
Axial CT scan with IV contrast medium at the level of the
maxillary sinus and nasopharynx: soft tissue mass in the left pterygopalatine fossa with
destruction of the bony boundary (1). The right pterygopalatine fossa is normal (2).
Coronal CT scan with IV contrast medium at the level of the anterior
sphenoid sinus: there is enlargement and erosion of the left foramen rotundum (1). The
right foramen rotundum is normal (2).
