title: Cardiac sarcoidosis: case report, workup, and review of the literature.
abstract: BACKGROUND
  Cardiovascular disease is the leading cause of death worldwide, with coronary heart disease being the most common manifestation disease. While deaths attributed to coronary heart disease are falling in the developed world, the number of patients with cardiomyopathy continues to increase. In this paper, the current literature on imaging modalities for infiltrative and inflammatory cardiomyopathies is reviewed, focusing on the three most common diagnoses, namely sarcoidosis, amyloidosis, and myocarditis.
  
  
  METHODS
  A 43-year-old male presented with palpitations and left ventricular systolic dysfunction for a second opinion following an initial nondiagnostic workup. The employed clinical and radiologic approach that led to a definitive diagnosis and disease-specific treatment is presented here.
  
  
  CONCLUSIONS
  The current algorithms and the strengths and weaknesses of the various radiologic techniques in establishing a diagnosis in patients who present with new onset cardiomyopathy are reviewed. Recommendations are provided regarding the selection between echocardiography, computed tomography radionuclide imaging, and magnetic resonance imaging in diagnosing the various causes of cardiomyopathy.
