ABSTRACT
INTRODUCTION: Hydatid disease is a parasitic infection caused by the development of the larval form of the Teania of Echinococcus granulosus. It is endemic in many regions of the world such as the Mediterranean basin. Location without pericardial cardiac involvement is extremely rare. In this case study, we will elaborate the case of an intra-pericardial hydatidosis disease without cardiac location revealed by a tamponade. OBSERVATION: AA is a 60-year-old man with no pathological history and who was admitted for a tamponade assessment. Indeed, the cardiovascular examination showed a muffling of the heart sound and signs of a right heart failure. Besides, the ECG shows a microvoltage, and the chest radiography shows cardiomegaly. Moreover, the transthoracic echocardiogram confirmed the presence of an abundant pericardial effusion along with signs of a tamponade. It also reifies the presence of, at the intra-pericardial level, a multiple vesicular formation giving a cluster of grapes highly suggestive of an intra-pericardial hydatid disease. An emergency surgical drainage allowed removing about two liters of suspicious fluid along with cysts and white membranous. The pathological examination of the membranous confirmed the diagnosis of a pericardial hydatid cyst. The performance of a chest CT and an abdominal ultrasound's scan to identify other locations shows no further anomalies. The patient was put under medical treatment (Albendazole(®)) and is showing a good clinical improvement. CONCLUSION: The intra-pericardial hydatid disease is another cause of tamponade not to fail despite its rareness, as it is endemic to North African countries.
