This case presents a rare infectious cause of stroke and air embolism involving a pulmonary abscess and pulmonary vein thrombosis. Early detection, diagnosis, and appropriate treatment of infected systemic embolism in young patients are crucial to prevent serious complications.
Background: Although most stroke patients have underlying vascular risk factors, it is important to consider infectious causes of stroke in young adults without traditional risk factors or patients with cryptogenic stroke. Pulmonary vein thrombosis and air embolism can potentially cause cerebral infarction. However, the association between infection and pulmonary vein thrombosis or air embolism is often overlooked. In this case, we present a rare infectious cause of stroke and air embolism involving a pulmonary abscess and pulmonary vein thrombosis.Case presentation: A 37-year-old male patient initially presented with right-sided pneumonia. During treatment at a local hospital, he developed headaches and left limb weakness. Subsequently, he was transferred to our hospital due to septic shock. Neurological evaluations revealed multiple brain foci and thrombosis in the right superior pulmonary vein. Following treatment with broad-spectrum antibiotics and anticoagulants, the patient's clinical symptoms and inflammatory markers showed improvement. However, a computed tomography scan revealed the formation of a pulmonary abscess, and the patient experienced coma and epilepsy after severe coughing with massive hemoptysis. Multiple air embolisms were observed in the brain computed tomography. Eventually, the patient's family chose to discharge him from the hospital.Conclusions: This case highlights the rare and complex etiologies of stroke associated with infection in a young patient. Early detection, diagnosis, and appropriate treatment of infected systemic embolism in young patients are crucial to prevent serious complications.
