This is Barry Bellosis, one of the musculoskeletal radiology fellows at Stanford University. 18 year old baseball player was struck with glancing blow while batting, concerned for orbital fracture. In the setting of maxillofacial trauma, CT maxillofacial without contrast is the preferred imaging modality of choice, such as the patient in this case. This is an axial bone kernel reformat of this patient showing a depressed fracture of the medial orbital wall with herniation of the fat content medially. Additionally, we can see the soft tissue pacification of the ethmoid air cells, likely representing hemorrhagic content. We also evaluate this in coronal reformats and here we can see the depression fracture deformity of the medial orbital wall with herniation of the fat content medially and inferiorly. Additionally, the medial rectus muscle is slightly and medially displaced compared to the contralateral side.
