Echinococcosis complicated by purulent pericarditis.

Area of Science:

• Medicine
• Parasitology
• Cardiology

Background:

• Hydatid disease, caused by Echinococcus tapeworms, can manifest in various organs.
• Cardiac involvement, though rare, presents significant diagnostic and therapeutic challenges.
• Purulent pericarditis is a severe infection of the pericardial sac.

Observation:

• Three cases of purulent pericarditis complicating echinococcosis are presented.
• One case involved a ruptured myocardial hydatid cyst with secondary infection and disseminated germinal membrane.
• Two cases involved infected hepatic hydatid cysts forming a fistula to the pericardium post-surgery.

Findings:

• Echocardiography and surgical findings confirmed the hydatid origin of the pericarditis.
• The diverse origins (myocardial vs. hepatic) highlight the protean nature of cardiac echinococcosis.
• Superinfection of hydatid cysts is a critical pathway to purulent pericarditis.

Implications:

• These cases underscore the importance of considering echinococcosis in patients with purulent pericarditis, especially with hepatic or cardiac history.
• Early recognition and appropriate management are crucial for improving outcomes in this rare but serious complication.
• Further research into diagnostic markers and treatment strategies for cardiac echinococcosis is warranted.
