Coronal CT, Bone Window. Ethmoid and Maxillary sinusitis with deviated septum. (I'm thinking it is bone window because of the detail of the bone, yet there is soft tissue differences also.

Xray (I believe it is the open-mouth Waters PA axial transoral projection). With only a thin bone separating the sinuses from the brain, the infection could pass through the bone and infect the meninges and/or the brain itself. The infection could also spread to the orbits with a potential to cause blindness. In addition, another rare but possible outcome would be aneurysms or blood clots which have the potential to be fatal.

Nasal Polyps
http://www.webmd.com/allergies/sinus-pain-pressure-9/slideshow-sinusitis
Chronic Sinusitis is inflamation of the sinuses that lasts months (about three) to years. When the sinuses are obstructed mucus and on occasion pus builds up in the sinuses. This leads to pressure and pain.
Causes include:
allergies
polyps
nasal fractures
viral or bacterial infection
Symptoms include:
pain and pressure in forehead, nose, between the eyes, in the cheek, and or teeth
also congestion, postnasal drip, bad breath, fever, and thck nasal discharge
Diagnosis:
fever, tenderness in face in sinus areas, inflammation and mucus in nose and throat,
nasal polyps, deviated septum, enlarged lymph nodes are all indicative of sinusitis.
Sometimes an allergy test is performed to see if allergies are the culprit. CT & or MRI (usually
CT) of the sinuses will indicate whether there is structural blockage or not.
