Abstract
BACKGROUND Giant cell tumors of the bone (GCTB) are rare, locally aggressive benign neoplasms that primarily occur in the metaphyses of long bones. In less than 2% of cases, GCTBs arise in the spine, predominantly below the sacrum. We report the clinical manifestations, diagnostic approach, and successful surgical treatment of a patient with a GCTB of the thoracic spine. CASE REPORT A 21-year-old female patient presented to the Emergency Department with back pain and upper motor neuron syndrome. A thorough clinical and imaging examination revealed a tumor and pathological fracture of the T7 vertebra. Histopathological analysis confirmed the diagnosis of a GCTB. The tumor was successfully excised surgically via a posterior thoracic approach, including bilateral decompressive laminectomy, lateral costotransversectomy, and posterior corpectomy, followed by transpedicular instrumentation of the T5-T6 and T8-T9 vertebrae, and anterior arthrodesis with an autologous graft. The patient also received adjuvant radiotherapy. One year later, the patient had no signs of recurrence or physical limitations. CONCLUSIONS GCTBs located in the thoracic spine are uncommon and pose a significant challenge for healthcare professionals due to their non-specific clinical manifestations and the need for a multidisciplinary approach to their management. This case highlights the diagnostic and therapeutic implications of a GCTB of the thoracic spine and describes a successful surgical strategy resulting in complete recovery. The presented case adds to the limited published literature on GCTBs in this unusual location and further elaborates on their presentation and management.
