Long-term epilepsy associated tumors, abbreviated LEAT is an umbrella term for rare tumor entities in patients that do not match current WHO diagnostic criteria.

General


Examples

  • Papillary glioneuronal tumor [1]
  • Angiocentric glioma [2]
  • Isomorphic diffuse glioma [3]
  • Multinodular and vacuolating neuronal tumor of the cerebrum [4]
  • Polymorphous low grade tumor of the young [5]


Criteria

See [6]

  • Seizures <18 years.
  • Temporal lobe location.
  • Mostly benign appearance (as in WHO grade I).
