The Enneking classification of benign lesions applies to benign spine tumors, as follows:

  • Stage 1 - Latent
  • Stage 2 - Active
  • Stage 3 - Aggressive

Stage 1 lesions are usually asymptomatic and are discovered incidentally. Stage 2 lesions usually present with symptoms; most commonly, pain is in the area of the lesion. Stage 3 lesions are locally aggressive and can actually metastasize. [12]
