Metallic orbital foreign body on MRI

Case contributed by Dr Chris O'Donnell

Presentation

Presented for routine brain MRI for long-standing headaches. Answered "no" on the safety sheet for past history of metal in the eyes or metal worker.

Patient Data

Age: 58
Gender: Male

An image that induces panic in any MRI technician.  Marked susceptibility artefact due to metal projected over the left orbit causing distortion to the image!

Small, rounded, metallic foreign body outside the globe in the inferior eyelid without gross artefact on CT.

Case Discussion

An absolute contraindication to MRI is the presence of a metallic foreign body in the globe.  In this case there was extreme concern on the initial MRI imaging (it was immediately terminated on seeing this artefact), but fortunately CT showed the metal to be outside the globe and the patient suffered no ill-effects.
