RESUMEN
INTRODUCTION: The hydatid cyst (HC) of the right ventricle (RV) is an extremely uncommon and a serious location that can cause sudden death following pulmonary embolism, obstruction of the valvular orifice or anaphylactic shock. CASE PRESENTATION: We report a case of a 14 years-old girl with a HC of the RV. Surgical excision of the HC under Cardiopulmonary bypass (CPB) was successful in managing this rare case. CLINICAL DISCUSSION: Cardiac HC is extremely rare. It represents only 0.5-2% of all hydatid cases. However, RV location is very severe. It has a tendency to rupture intracavitarily and causes sudden death in 30% of cases. Its diagnosis is based on echocardiography, computed tomography scan and magnetic resonance imaging. The surgical treatment under CPB with anthelmintic therapy seems to improve the prognostic outcomes. CONCLUSION: Cardiac HC must be always suspected in endemic countries, especially in patients with a family history of HC.
RESUMEN
INTRODUCTION: The rupture of the hydatid liver cyst in the pericardium is a very exceptional and serious complication that can cause sudden death following cardiac tamponade or anaphylactic shock. CASE PRESENTATION: We report a case of a 25 years-old woman with a massive pericardial effusion due to fistulization of hepatic hydatid cyst. Surgical closure of the fistula and the resection of the tow hydatid cysts were successful in managing this rare case. DISCUSSION: Hepato-pericardial fistula is an extremely rare complication of hydatid liver cyst. Only 6 similar cases were previously reported in the literature. The Hepato-pericardial fistula may result in an acute pericarditis that progress to either cardiac tamponade or constrictive pericarditis. Its diagnosis is based on ultrasound and CT imaging. The surgical treatment with supportive therapy seems to improve the outcomes. CONCLUSION: Pericardial effusion secondary to rupture of hepatic hydatid cyst should always be suspected in endemic countries.
RESUMEN
A 24-year-old male was admitted for syncope and epigastric pain and fever. Biological examination showed leukocytosis and marked eosinophilia, the brain computed tomography (CT) was normal. The echocardiography revealed a voluminous mass in the free wall of the right ventricle compressing the right cavities without communication confirmed with thoracic CT. Hydatid serology was positive. Early and urgent surgery was decided. The postoperative period was uneventful and the patient was discharged home on albendazole. Hydatid cyst is an endemic parasitic infection in cattle-breading countries, and migration has played a significant role to expand this infection worldwide. Cardiac hydatidosis is rare (0.5-2%) in comparison with hydatidosis of the liver (65%) and lung (25%). The right ventricle location is even rarer, 10% versus 60% for the left ventricle, and can cause fatal complications such as anaphylactic shock, dissemination, and pulmonary embolism.
