Description

Diagnostic imaging of pseudoarthrosis and collapsed vertebral body after compression fracture caused by osteoprosis is comparatively easy from vacuum cleft in X-ray or fluid pool around the fractured vertebral body in MRI. We report a case of vertebral compression fracture that was suspected of mass-like lesion requiring differential diagnosis. A 53-year-old woman was diagnosed with malignant rheumatoid arthritis (MRA). Her chief complaint was lumbar backache and lassitude of both lower extremities. Lumbar backache developed from the front for three months. The first lumber vertebra disappeared in X-ray partially, and vacuum cleft or osteosclerosis images were not found. Tumor like density connected with the vertebral body in para vertebral area was revealed on MRI. We performed front and back fixation. There was a large quantity of ooziness, psammous in the mass. The pathologic findings were fibrocartilage, hyaline cartilage, and small inflammatory granulation tissue of bone tissue. The nonspecific inflammatory tissue was thought to add to the vertebral compression fracture caused by rheumatoid arthritis.
