Case ReportHistory
Exam
Findings
Preseptal Soft tissues and Orbital Adnexa
The preseptal soft tissues over the right orbital frontal regions are swollen/edematous with radiodense debris in the skin and subcutaneous tissues. There is one bubble of air in the conjunctival sac which is not likely consequential.
Eyes and Optic nerves
The eye is not decompressed or enlarged. The anterior segment structures of the eye are normal. There is no evidence of a subretinal, subchoroidal, subhyaloid or intravitreous hemorrhage or other fluid collection. There is no definite evidence of hemorrhage in or along the optic nerve and/or sheath. Signs of tension orbit are not present.
Orbits
There is a complex right orbital blow in type injury with upward displacement of the orbital floor and non to minimally displaced fractures of the greater wing and body of the sphenoid bone extending into the root of the zygoma but most significantly into the right optic canal.
The extraconal orbital fat is minimally swollen along the infraorbital canal; however, extraocular muscles, orbital apex and superior orbital fissure appear otherwise normal.
Brain
There are is a small likely epidural hematoma along the floor of the right middle cranial fossa.
Other Findings
There are no other significant abnormalities present.
