Purpose or Case Report: 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 Relapse of Medulloblastoma;
- Vertebral Ewing Sarcoma;
- Vertebral Osteoid Osteoma;
- Vertebral Chordoma;
- Vertebral Aneurysmal Bone Cyst;
