Demographics:

Indication:
Left eye injury
Findings
- Acute minimally displaced fractures of the left orbital floor and medial left orbital wall
- Partial herniation of the inferior rectus muscle and orbital fat through the orbital floor fracture with hourglass appearance of the muscle as it traverses the fracture plane
- Fluid in the right mastoid antrum and in posterior right mastoid air cells
- Mucoperiosteal thickening of the right greater than left maxillary sinuses and ethmoid air cells
Diagnosis
Trapdoor fracture
Sample Report
Acute minimally displaced left orbital floor trapdoor fracture with partial herniation of the inferior rectus muscle and orbital fat through the orbital floor fracture. Hourglass appearance of the muscle as it traverses the fracture plane is highly suggestive of muscular impingement.
Acute minimally displaced left medial orbital wall fracture. No retrobulbar hemorrhage. Globes are intact.
Fluid in the right mastoid antrum and in posterior right mastoid air cells without definite temporal bone fracture. Recommend correlation with point tenderness and with clinical signs of mastoiditis.
Mucoperiosteal thickening of the right greater than left maxillary sinuses and ethmoid air cells.
