Pulmonary hemorrhage induced by epileptic seizure

Abstract We report a 35-year-old man who presented with pulmonary hemorrhage induced by an epileptic seizure. He had experienced recurrent episodes of massive hemoptysis after epileptic seizures since the age of 28 years. He was admitted to Kyoto University Hospital with massive hemoptysis and hypoxia after an epileptic seizure of a few minutes’ duration. Radiographic signs of infiltrations and hemorrhagic bronchoalveolar lavage fluid were observed. He was intubated and successfully treated with anti-epilepsy drugs and corticosteroids. Epileptic seizures may have induced increased pulmonary vascular permeability and structural damage to the blood–gas barrier, which may have caused pulmonary hemorrhage. Pulmonary hemorrhage could be in the list of differential diagnoses of hemoptysis in patients with epilepsy.
