PET/CT in Primary Tumors of the Osseous Spineent imaging modalities is to recognize typically benign disease, in which further invasive staging can be omitted, and patients with a suspected malignancy, who should be referred for biopsy. In most cases, these questions can be answered by means of conventional radiography, computed tomography (CT

Imaging-Guided Biopsyignificantly. Unlike spinal metastases, primary tumors localized to a single location may offer the potential for curative resection. However, a spinal biopsy that is not performed correctly can compromise a patient’s survival. The high accuracy, lower costs, reduced complication rate and morbidity,

Bone Islande islands are thought to result from failure of bone resorption during endochondral ossification process or due to congenital etiology or failure of the development during childhood. The prevalence of bone islands is variable; the incidence of bone islands in the spine ranges between 1% and 15% on i

Osteoid Osteoma and Osteoblastomaturnal pain. Regarding osseous tumors of the spine, characteristic morphology is encountered in osteoid osteoma and nonaggressive osteoblastomas (giant osteoid osteomas), and in these cases, radiological imaging can make a specific diagnosis, especially when the radiologist has chosen thin-sliced co

Giant Cell Tumor of the Spinesiometaphysis of long bones, spinal lesions are relatively uncommon. The pathologic features of GCTs involve a vascularized stroma composed of spindle-shaped mononuclear cells and multinucleated giant cells. Although GCTs are typically considered benign, approximately 10% may exhibit malignant behav

Spinal Osteosarcomas neurologic deficit is frequent, indicating a locally advanced disease at presentation. The diagnosis is made by histology. MRI is the imaging modality of choice for local staging. Chest CT and bone scintigraphy is the classic combination for distant staging. Whole-body MRI, 18-FDG-PET/CT, and 18-F

Fibrous Dysplasia of the Spineentire skeleton..It is caused by a mutation of the gene GNAS1 resulting in a maturation defect of bone-forming mesenchymal tissue, leading to poorly mineralized woven bone trabeculae surrounded by fibrous tissue..Involvement of the spine is uncommon and may involve any vertebral element at every ver

Aneurysmal Bone Cyst and Other Cystic Lesionsyoung adults and generally occurs in long bones. The spine is involved in 8.7–19% of cases with a predilection for the posterior arch. ABC presents typically as a lytic and expansile lesion with internal bony septa. MRI is the modality of choice to show the blood-filled cavities with fluid-fluid lev
