Epileptic seizures as a cause of unilateral pulmonary edema.

We report three patients with recurrent tonic-clonic seizures associated with unilateral pulmonary edema. Each lung was involved on separate occasions in one patient. The mechanisms of seizure-related pulmonary edema are discussed. Although accurate diagnosis of unilateral postictal pulmonary edema may be difficult because of its rarity, not all pulmonary abnormalities that follow seizures represent pneumonia.
