Differential Diagnosis of Skull and Spine Disorders

  1. NONTUMOROUS
    1. Extramedullary hematopoiesis
      • hemolytic anemia / myelofibrosis
    2. Pott abscess
      • calcification in a large paraspinal abscess WITHOUT new bone formation / sclerosis favors tuberculosis
    3. Castleman disease
      • intense homogeneous enhancement
      • frequent calcifications
  2. TUMOROUS
    1. Lymphoma
      • faint homogeneous enhancement
    2. Neurogenic tumor: neurofibroma, schwannoma, ganglion tumor
      • commonly erosions / scalloping of vertebrae ± ribs
      • moderate homogeneous enhancement
    3. Pleuropulmonary synovial sarcoma
    4. Extraadrenal neuroblastoma
    5. Extraskeletal Ewing sarcoma

Neurogenic Tumor

  1. Nerve sheath
    1. Schwannoma
    2. Neurofibroma
    3. Malignant nerve sheath tumor
  2. Ganglionic cell
    1. Ganglioneuroma
    2. Ganglioneuroblastoma
    3. Neuroblastoma
  3. Paraganglionic cell
    1. Paraganglioma
    2. Pheochromocytoma
