Sacral Giant Cell Tumor-Induced Cauda Equina Syndrome: Case Report with Successful Management.

Sacral giant cell tumor (GCT) is a rare entity. It often presents late after massive enlargement of tumor. Here we are reporting a case of sacral GCT treated successfully at our institute. A 30-year-old male patient presented with paraplegia, significant sensory disturbance below L2 level, along with severe vesicorectal dysfunction. On imaging, giant mass was seen filling the sacrum with homogenous enhancement and flow voids from L5 level to S4 level. The patient underwent surgical exploration with L4-5 decompressive laminectomy, near-total resection of tumor, and lumboiliac fixation. The patient recovered symptomatically in postoperative period. Sacral GCT is a rare but treatable lesion. Its presentation as sudden cauda equina syndrome is rare, but final management should be aggressive with en bloc resection and fixation.
