Summary
A rare case of Echinococcus granulosus infection in the heart led to sudden death due to arterial embolism. This diagnosis should be considered in individuals from endemic areas presenting with unexplained sudden death.
Area of Science:
- Cardiology
- Parasitology
- Pathology
Background:
- Echinococcus granulosus infection, typically affecting organs like the liver and lungs, can rarely involve the heart.
- Cardiac echinococcosis often remains asymptomatic until a critical event occurs.
Observation:
- A 45-year-old woman with no prior illness presented with sudden shortness of breath, seizures, and rapid death.
- Autopsy revealed a large hydatid cyst in the left heart, with rupture causing arterial embolism.
- Microscopic examination confirmed Echinococcus granulosus, despite negative antibody tests.
Findings:
- Ruptured cardiac hydatid cyst leading to fatal arterial embolism.
- Asymptomatic Echinococcus granulosus infection presenting as sudden death.
- Diagnostic challenges due to lack of serological evidence.
Implications:
- Highlights the importance of considering cardiac echinococcosis in cases of sudden death, especially in individuals from endemic regions.
- Underscores the potential for severe, life-threatening complications from seemingly asymptomatic parasitic infections.
- Emphasizes the need for awareness among clinicians regarding rare presentations of Echinococcus granulosus.
