This is a case series of nine patients of Giant (>5cm) primary spinal bony extra-axial tumors operated at a single center from Jan 2011 to Nov 2023. The data was tabulated and we analyzed presentation, imaging, treatment and outcome of these patients with review of literature. Mean age of presentation for benign tumors was 24.5 years whereas it was 46 years for malignant tumors. Mean duration of presentation for benign lesion was 15.75 months whereas for malignant lesions it was 3.4 months. 5 cases out of 9 (55%) were in dorsal region, 1 case (11.11%) in cervicothoracic region and 3 cases (33.33%) were in sacral region. All patients presented with symptoms of back pain, 7 (77.77%) had motor symptoms, 5(55%) presented with sensory symptoms and 5(55%) with bladder bowel. Out of 4 benign lesion one underwent intralesional excision, rest underwent marginal en bloc excision. Out of 5 malignant lesion one underwent intralesional excision, rest underwent marginal en bloc excision. Out of 4 benign lesions two patients (50%) did not show any improvement at 1 month follow up. Out of 5 malignant lesion 1 patient (20%) did not show any improvement at 1 month follow up. Giant primary bony spinal tumours are rare entities. Early diagnosis and surgical treatment are paramount for tumour control and functional improvement.
