CHONDROMYXOID FIBROMA OF BONE PRESENTING AS CHRONIC BACK PAIN

Objective: To discuss a case of chondromyxoid fibroma presenting with low back pain. Clinical Features: A 50-yr-old man had an 8-yr history of low back pain. This was diagnosed and treated as arising from the d isc and caused by spinal stenosis. Magnetic resonance imaging findings supported the clinical findings. Years later, a plain radiograph of t he pelvis revealed an incidental abnormality of the right ilium, and t he patient was subsequently referred to a musculoskeletal tumor center for treatment. Intervention and Outcome: The lesion was surgically re moved and the defect was reconstructed via bone allograft. Conclusion: Such tumors are a rare cause of back pain. Tumors of the pelvis can a t times present as back gain. In cases of refractory back pain, an X-r ay of the pelvis can be a useful screening investigation. Chondromyxoi d fibromas are rare tumors best treated by excision if they are amenab le or by curettage and bone grafting procedures.
