title: Pelvic osteosarcomas causing lumbosacral nerve root compression presenting as herniated intervertebral disc: report of two cases.
abstract: Osteosarcomas of the pelvic bone are rare. Neurological complication of osteosarcomas in this location is also rare. Diagnosis is not always easy, and misdiagnosis may occur due to pelvic bone destruction and nerve root compression. We present two cases of pelvic osteosarcoma with lumbosacral radicular symptoms who were previously thought to have lumbosacral herniated intervertebral disc.
