Abstract:
STUDY DESIGN: This case report presents a rare case of pre-sacral giant schwannoma which originates from the S1 nerve root. OBJECTIVES: To discuss a surgical approach for removal of pre-sacral giant schwannoma and review the pertinent literatures. SUMMARY OF LITERATURE REVIEW: Pre-sacral tumors are unusual neoplasms that cause approximately one in 40,000 hospital admissions. Schwannoma represents only a small fraction of the many types of tumors that may be present in this region. Less than 1% of all spinal schwannomas occur in the sacrum. The treatment of this lesion is complete removal, which is curative. MATERIALS AND METHODS: A 46-year-old woman developed gradual back pain and radiating pain on her left lower extremity for about a year. There was no noted improvement with the use of conservative treatment. T1-weighted sagittal MRI reveals a large homogeneous low-signal intensity mass on left pre-sacral area and intrasacral extension of the tumor forming a dumbbell shaped mass. RESULTS: The tumor was completely removed by a combined anterior and posterior approach. The excised mass was cylindrical, measuring 8x4x3cm in size, which had originated from the S1 nerve root. It was histologically diagnosed as benign schwannoma. Satisfactory result was obtained after the complete removal of the mass. CONCLUSIONS: We report a case of the successful and complete removal of a pre-sacral giant schwannoma and the affected nerve root through a combined anterior and posterior approach.
