Abstract
Rheumatoid glanulomatous lesion of the lumbar spine has been reported only rarely. A 59-year-old female patient with a 19 year history of seropositive rheumatoid arthritis sufferred from low back pain. An X-ray of the lumbar spine showed a narrowing of the 4th disc and erosion including the apophyseal joint. A glanulomatous lesion between the 4th disc and the edge of the vertebral body was found on operating. Histological diagnosis of the glanulation was chronic non-specific inflamation.
