The histological findings in the heart in cases of fatal sepsis can show myocytolysis, interstitial fibrosis, necrotic contraction band, mononuclear infiltrates, and interstitial edema, which can be used in post mortem diagnosis of sepsis. Septic myocardial calcification is a very rare condition, and only a few cases have been reported in the literature. In general, the pathogenesis of the myocardial calcification has not been well clarified, but two pathogenic mechanisms have been universally recognized: metastatic or dystrophic. We present a rare case of sepsis-related myocardial calcification. Here we report a case involving a 72-year-old white male who was admitted to a hospital for a polytrauma caused by a motorbike accident. On the 110th day of hospitalization, the patient was diagnosed with a septic process and a subsequent transesophageal echocardiogram revealed the presence of a calcification on the right atrial wall. According to the medical history of the patient there were no systemic factors predisposing to calcium crystals deposition in tissues. Patient died due to multi-organ failure in the course of multimicrobial septic shock during the 149th day. The autopsy revealed both the presence of a greenish-brown formation and a greater consistency of the right atrial wall. The histological investigation of the right atrium wall showed a wide calcification area localized at subendocardial level, which contained fibrin deposition and was surrounded by fibrotic tissue.
