Title

METALLIC INTRAOCULAR FOREIGN BODY DISPLACEMENT DURING MAGNETIC RESONANCE IMAGING

Pages

  186-190

Abstract

 Purpose: To present a case of intraocular foreign body DISPLACEMENT during MRI. Patient and findings: A 34-year-old man was seen because of sudden pain in left eye after an MRI had been performed. Upon admission a large METALLIC FOREIGN BODY (FB) was visible in the anterior chamber. He gave history of penetrating trauma 18 years ago. The MRI was requested for low back pain. The FB was removed via a limbal incision. Postoperatively the patient had 20/30 vision despite a mild cataract, the retina was totally normal, and there was no evidence of siderosis. The electroretinogram was normal. On chemical analysis, the FB was composed of more than 99% iron. In this case, despite the large size of FB and its motion, there was no injury sustained by the posterior segment and only a mild cataract had developed. In spite of the large size of the FB, its chemical composition, and the long period of retention, there was no evidence of siderosis, which is remarkable. Conclusion: Movement and DISPLACEMENT of metallic foreign bodies by the magnetic field of MRI equipment is rare but possible. Patients should be screened prior to imaging by history and if considered suspicious or high risk, x-ray or CT scan may be needed to rule out the possibility.
