The image findings, minimally invasive surgical procedures, clinical outcome were discussed, the literature was reviewed. Summary background data Primary benign teratomas retroperitoneum are rare. Extension these lesions into canal more In this report, by presenting a such extension, origin tumor, value computerized tomography magnetic resonance imaging (MRI) preoperative diagnosis approach for extended lesion discussed. Methods patient 24-year-old female who had low back pain bilateral sciatica 2 months. Preoperative MRI thoracic lumbar spines showed solid part residing right near neuroforamen L2-L3 extending canal. By performing L2-L4 hemilaminectomies mini approach, tumor removed en bloc one stage. Results Diagnosis confirmed pathologic examination. recovered well without any neurologic deficits, recurrence has not been found 9 years postoperatively.
