CT best for diagnosing suspected wooden foreign objects in the eye

By Kate Madden Yee

CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.

A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.
