Introduction: Myocardial steatosis, a poorly documented pathology, is characterized by the accumulation of abnormal amounts of triglycerides in the cardiomyocytes. Myocardial steatosis is generally asymptomatic, but it can be the cause of heart failure. It is primarily of hypoxic or metabolic origin.
Case Report: We report a case of postmortem diagnosis in a 53-year-old male patient, without known his pathological history, who was a victim of sudden death from abdominal pain. The autopsy revealed diffuse atheromatous cardiac, aortic, and hepatic lesions.
Conclusion: It is very common for myocardial steatosis to be diagnosed postmortem due to its nonspecific symptomatology. The risk of mortality and morbidity could be reduced through a healthy lifestyle and regular biological examination to identify risk factors.
