Background: Pulmonary embolism remains a disease which needs high clinical suspicion to prevent mortality and morbidity. More so in young healthy individuals, suspicion is very low as compared to old age individuals with multiple co-morbid conditions. Pulmonary embolism carries high mortality if not suspected and treatment initiated as early as possible. Case Report: This is a case report of young male who presented with acute onset of breathlessness and later diagnosed as a case of pulmonary thromboembolism. Conclusion: Pulmonary embolism should be kept a possibility in a young adult presenting with acute onset of dyspnea.
