Abstract
We report three cases of sacral tuberculosis, Intra-osseous sacral schwannoma and Aneurysmal bone cyst presenting as refractory low back pain with non-specific clinical features delaying in diagnosis of these rare tumors. All three tumours presented to us as intervertebral disc prolapse and upon failure of conservative treatment led to further detailed radiological evaluation. Awareness of these rare tumours as differential diagnosis and along with other common benign and malignant tumours of the sacral region helps in pre-operative planning regarding surgical approach and clearance. Intra-operative good clearance and biopsy is mandatory for accurate management and to prevent recurrence.
