Abstract
An 80-year-old male was admitted to the department of neurology for intensive examination and treatment of peri-optic nerve inflammation. Magnetic resonance imaging examination could not be conducted because a magnetic resonance imaging examination at a previous clinic revealed a subcutaneous foreign body on his head, possibly a piece of metal. He was referred to our department for the removal of this foreign body. There was no traumatic scar in the skin and we could not identify this subcutaneous foreign body by physical examination and superficial echography, but radioscopy could find this subcutaneous material and we could remove this foreign body under the guidance of the radioscopy.
