Sarcoidosis is a multisystemic granulomatous disease of unknown cause occurring in young adults. Cardiac sarcoidosis patients are at increased risk for atrioventricular blocks and ventricular arrhythmias. Sinus node dysfunction is scarcely reported. We report a case of cardiac sarcoidosis revealed by a sinus node dysfunction and focus on cardiac and thoracic imaging to guide diagnosis. Sinus node dysfunction may be the first manifestation of cardiac sarcoidosis. In unexplained sinus node dysfunction in young patients, advanced cardiac imaging is a key to cardiac sarcoidosis diagnostic. Early recognition of cardiac sarcoidosis enables to start immunosuppressive treatment and discuss implantable cardioverter defibrillator implantation.
