Insights
A rare case of isolated pericardial hydatid cyst causing cardiac tamponade was successfully treated. Surgical removal and albendazole therapy led to a full recovery without recurrence.
Area of Science:
- Cardiology
- Parasitology
- Thoracic Surgery
Background:
- Hydatid cysts, caused by Echinococcus granulosus, typically affect the liver and lungs.
- Pericardial hydatid cysts are exceptionally rare, with few reported cases.
- Cardiac tamponade is a life-threatening condition requiring urgent intervention.
Observation:
- A 47-year-old man presented with acute pericardial tamponade due to an isolated pericardial hydatid cyst.
- Initial transthoracic echocardiography confirmed the cyst and pericardial effusion.
- Emergent pericardial drainage was performed to stabilize the patient.
Findings:
- Computed tomography revealed a pericardial cyst without myocardial involvement.
- Complete surgical excision was achieved via anterior thoracotomy, avoiding cardiopulmonary bypass.
- Postoperative albendazole treatment was administered.
Implications:
- This case highlights the possibility of treating isolated pericardial hydatid cysts with less invasive surgical approaches.
- Early diagnosis and intervention are crucial for managing this rare cause of cardiac tamponade.
- Successful surgical management and antiparasitic therapy can lead to excellent long-term outcomes.
Abstract:
We report a case of a 47-year-old man with isolated pericardial hydatid cyst (without myocardial involvement) that presented as acute pericardial tamponade. After initial investigation and transthoracic echocardiography, emergent pericardial drainage was performed for downgrading the urgency of a definitive treatment for a hydatid cyst. A computed tomography examination after the pericardial drainage showed a pericardial cyst without heart muscle involvement, making the treatment possible through anterior thoracotomy and without performing cardiopulmonary bypass. Complete surgical removal of the cyst was performed. The postoperative course was uneventful. The patient received postoperative albendazole treatment. He remained asymptomatic and no recurrence was observed during a 1-year follow-up period.
