STUDY DESIGN: Case report. OBJECTIVES: To present a rare case of a previously operated giant schwannoma located in the sacrum, and to make some considerations regarding diagnostic modalities and treatment options. SUMMARY OF BACKGROUND DATA: Large sacral schwannomas with anterior cortex erosion and associated intrapelvic extension are uncommon. Only a few case reports and small series have been published. There is no established consensus regarding diagnostic modalities, necessity for histologic diagnosis before surgery, or best surgical option. METHODS: The patient presented with a 2-month history of right sciatica and severe low back pain. After a histopathologic diagnosis and a complete set of image studies, the resection of the tumoral mass was planned posteriorly. RESULTS: Seventeen months after tumor resection, the patient has a good clinical outcome, and there are no radiologic signs of instability or recurrence. CONCLUSIONS: Considering the experience of the few cases reported in the world literature, the management of this tumor appears to grant favorable results, recurrence being the most frequent complication.
