LUMBAR RADICULOPATHY CAUSED BY A LOST SILVERCLIP

The case of an adult patient with lumbar radiculopathy (L:4) caused by a migrated silverclip, which was probably lost during the successful extirpation of a cerebellar tumor many years before is presented. The clip was removed surgically and the nerve root was submitted to a part ial neurolysis. Increased tension in the root due to corrosion of the clip and scar formation is the proposed pathophysiological mechanism i n this case.
