Giant Cell Tumour of the Spine.

Giant cell tumour (GCT) is a benign bone tumour characterised by osteoclastic-like multinucleated cells. This tumour predominantly occurs in adults during the third decade of life, commonly in the distal femur, proximal tibia, distal radius, and sacrum. Treatment options include wide local excision with possible adjuvant therapy depending on tumour size and site. We present a case of an 18-year-old lady with no prior medical history complaining of worsening insidious onset localised back pain and preceding numbness of the bilateral lower limbs, diagnosed with a giant cell tumour of the spine (T11).
