Case Discussion

The typical plain radiograph appearances of a teardrop sign observed in inferior orbital wall fractures.   This represents intraorbital fat (+/- inferior rectus muscle) which has protruded through an inferior orbital wall fracture.

This type of radiograph may feature in a rapid reporting examination set for the FRCR or other fellow examinations.
