Masses of both benign and malignant origin can occur in the spine and vertebrae, as well as in the paravertebral region, with subsequent vertebral and/or spine invasion. Although definitive diagnosis is established through anatomopathological evaluation, imaging appearance may help narrow the diagnosis and allow prompt management. The aims of this presentation are: - To discuss the several entities affecting the spine and vertebrae regarding their pathophysiology, clinical presentation and treatment; - To demonstrate their radiological appearance, mainly in computed tomography (CT) and magnetic resonance (MR) imaging; - To propose an illustrative guide for reference, highlighting their differential diagnoses in imaging. The following teaching cases from our radiology department will be presented: - Medullary Ganglioneuroblastoma; - Medullary Astrocytoma; - Medullary Myxopapillary Ependymoma; - Medullary Lipoma; - Medullary Epidermoid Cyst; - Spinal Canal Shwannoma; - Spinal Canal Metastasis of Ependymoma; - Spinal Canal Relapse of Medulloblastoma; - Vertebral Ewing Sarcoma; - Vertebral Osteoid Osteoma; - Vertebral Chordoma; - Vertebral Aneurysmal Bone Cyst; - Vertebral Osteochondroma; - Vertebral Fibrous Dysplasia; - Osteoblastoma; - Vertebral Hemangioma; - Paravertebral Extrarenal Rabdoid Tumor; - Paravertebral Plexiform Neurofibroma; - Paravertebral Osteosarcoma Relapse; - Neuroblastoma with spinal canal invasion.
