Abstract

|
Pulmonary embolism is a devastating disease that causes significant morbidity and mortality, however, seizure as a presentation of pulmonary embolism is rare. We experienced two such cases of a 25- and a 59-year-old male who visited the emergency center because of new onset seizure activity with no structural lesions by MRI or CT. Despite having alert consciousness, they were found to have hypoxemia of unknown cause with EKG abnormality. Therefore, we performed bedside ultrasound and CT angiography; pulmonary embolism was then diagnosed. The patients had similar patterns-risk factors, deep vein thrombosis, abnormal EKG, hypoxemia, tachycardia, and seizure. Diagnosis of pulmonary embolism is very confusing, particularly in cases presenting with seizure. Therefore, we suggest that physicians should be more aware of the importance of considering pulmonary embolism within the differential diagnosis for unexplained new onset of seizure activity.
