Abstract:
STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of intradural disc herniation (IDH) around conus medullaris. SUMMARY OF LITERATURE REVIEW: IDH is rare with an incidence of less than 1% of all lumbar disc herniations. It is important to differentiate IDH from other condition with accurate diagnosis and subsequent surgical treatment. IDH has a higher risk of neurologic deficit, like conus medullaris syndrome and cauda equina syndrome. MATERIALS AND METHODS: A 62 year-old male was affected by lumbar back pain radiating to the anterolateral aspect of the right thigh for 5 days. MRI showed a mass that existed on the anterior portion of the conus medullaris. We performed partial laminectomy at the L1-L2level. The mass located anteriorly in the intradural space was eliminated after durotomy by a posterior approach. RESULTS: We confirmed the IDH for histopathology. CONCLUSIONS: IDH usually needs accurate differential diagnosis. Preoperative MRI scans are necessary to differentiate IDH from other intradural lesions. The confirmative diagnosis can be done only in the operative field.
