Case ReportHistory
Exam
Prior Study
Findings
Nasal Cavity and Nasolacrimal Drainage System
There is mucoperiosteal thickening in the nasal cavity bilaterally extending into the sphenoethmoidal recess on the left.
Sinuses
There is soft tissue swelling in the preseptal region just below the supraorbital ridge.
There is mucosal thickening in all of the sinuses.
The left frontal sinus shows likely chronic early mucocele formation. The acute or subacute disease in the frontal sinus erodes the inferior margin of the sinus as it forms the orbital roof. There is also thinning of the floor of the anterior cranial fossa as formed by the frontal bone and dehiscence along the slightly expanded appearing inner table of the left side of the frontal sinus.
Orbits
There is a subperiosteal orbital abscess on the left side which displaces the orbital periosteum inferiorly. There is associated edema spreading within the extraconal fat as well. The intraconal structures are deformed but not involved. The extraocular muscles are normal and there is no evidence of thrombosis of the superior ophthalmic or other orbital venous structures.
Eyes
There may be very minimal proptosis on the left side. There is no evidence of tension orbit or involvement of the globe.
Nasopharynx
There is no deeply infiltrating or necrotic/ulcerative process of the nasopharynx.
Intracranial
There is an epidural abscess along the orbital roof on the left side. There is edema in the adjacent frontal lobe without evidence of brain abscess. No other intracranial complications are identified.
Developmental variants
There are no significant anatomic variations present.
