Factors to consider:
  1. Neoplasm: yes or no?
    • Yes - hypercellular, composed of atypical fibrillar cells
    • No - may be infectious, inflammatory, toxic metabolic, traumatic, vascular, development or degenerative
  2. Primary or metastatic neoplasm?
  3. Glial, neuronal and other primary tumor considerations
  4. Correlate pathologic diagnosis with age, sex, location and imaging characteristics

  • Multiple lesions are often metastases, melanoma, medulloblastoma (late) or lymphoma
