Superior vena cava thrombosis and dilated cardiomyopathy as initial presentations of Behcet's disease

BACKGROUND: Bechet's disease (BD) is a relatively rare disease that causes recurrent oral and genital ulcers in addition to a variety of systemic manifestations. Concomitant superior-vena-cava (SVC) thrombosis and cardiac involvement with dilated cardiomyopathy (DCM) as initial presentations for BD is considered rare. CASE PRESENTATION: A 32-year-old-man presenting with intractable headaches and dyspnea. He was later diagnosed with SVC thrombosis and DCM. A diagnosis of BD was made after detailed history-taking. CONCLUSIONS: Cardiovascular manifisations can be the initial presentation of BD. We aim to highlight the importance of early clinical recognition of BD as a cause of DCM and SVC thrombosis.
