Diagnosis: Orbital blow out fracture medial
Facial CT in bone window shows a mild comminuted fracture of the central aspect of the right medial orbital wall (white arrows), with displacement of a segment of the lamina papyracea medially about 2 mm into the underlying ethmoidal air cell. There is minimal herniation of orbital fat with the fracture fragment. The medial aspect of the medial rectus muscle (asterisk) appears to contact the fracture margin (black arrow), and to some degree entrapment cannot be excluded. There is fluid opacification of a few right ethmoid air cells (white dotted arrows).
