Section 1 Submit Findings Case042 Findings Nasal Cavity and Nasolacrimal Drainage System There is mucoperiosteal thickening in the nasal cavity. Yes No There is ulceration or erosion of the nasal septum or turbinates. Yes No There is mucosal thickening of the posterior lateral walls of the nasal cavity, cribriform plate or the face of the sphenoid bone. Yes No There is infiltration of the fat surrounding the nasolacrimal sac. Yes No There is infiltration of soft tissues or bone erosion along the nasolacrimal fossa or canal. Yes No Sinuses There is soft tissue swelling anterior to the frontal sinus or in the soft tissues surrounding the maxillary sinuses. Yes No There is mucoperiosteal thickening in the sinuses. Yes No There is mucosal enhancement in the sinuses. Yes No There is an air fluid level in the frontal sinus. Yes No There is bone erosion along the walls of any affected sinuses. Yes No There is an appearance of bone expansion, due to regressive remodeling and suggestive of pre-existing mucocele, along the walls of any affected sinuses. Yes No Orbits The extraconal orbital fat is abnormal. Yes No There is a subperiosteal abscess or edema along the medial wall, roof or floor of the orbit. Yes No The extraocular muscles are swollen or otherwise abnormal. Yes No There is bone erosion along the walls of the orbit. Yes No The intraconal orbital fat is infiltrated. Yes No The orbital apex and the superior and inferior orbital fissures are infiltrated. Yes No The superior and/or inferior ophthalmic veins are dilated or thrombosed. Yes No Eyes Proptosis is present. Yes No The optic nerve is stretched in appearance. Yes No The posterior aspect of the globe is tented in appearance. Yes No The uveal scleral margin of the globe is swollen or enhancing abnormally. Yes No Signs of tension orbit or endophthalmitis are present. Yes No Nasopharynx There is a deeply infiltrating or necrotic/ulcerative process of the nasopharynx. Yes No Intracranial There is a subperiosteal fluid collection or abscess along the boney walls of the anterior or middle cranial fossa. Yes No There is an epidural fluid collection or abscess along the boney walls of the anterior or middle cranial fossa. Yes No There is a subdural fluid collection or abscess along the boney walls of the anterior or middle cranial fossa. Yes No There is a subdural fluid collection or abscess along the falx cerebri or within the tentorium. Yes No There is evidence of thrombus, thrombophlebitis or other occlusive or inflammatory process of the cortical veins, sphenoparietal sinus or sagittal sinus. Yes No There is evidence of thrombus, thrombophlebitis or other occlusive or inflammatory process of the cavernous sinus. Yes No There is evidence of inflammation of the distal internal carotid artery. Yes No There is evidence of an infectious aneurysm. Yes No There is brain edema specifically involving the frontal and temporal lobes. Yes No There is cerebritis specifically involving the frontal and temporal lobes. Yes No There is brain abscess specifically involving the frontal and temporal lobes. Yes No There is likely meningitis, meningoencephalitis with complicating hydrocephalus or brain herniation. Yes No Developmental variants The anterior ethmoid arteries are on a mesentery. Yes No The medial walls of the orbit position are abnormal due to their position or a significant dehiscence. Yes No The overall cephalocaudal dimensions of the ethmoid complex are unusual small. Yes No The olfactory fossa has an abnormal depth relative to the roof of the ethmoid complex and the cribriform plate has a significant dehiscence. Yes No The carotid artery and optic nerves adjacent to the sphenoid sinus are in an abnormal position and/or the overlying bone shows significant dehiscence. Yes No
