Hydatid Cyst of the Interventricular Septum Case Report and Literature Review

Hydatidosis is a frequent pathology which is still endemic in the kingdom of Morocco. Cardiac localization of hydatid cysts is rare representing 0.5 to 2% of all clinical forms of this condition. Hydatid cysts are usually observed in the left ventricle whilst interventricular septum localization is exceptional. The principal diagnostic and preoperative investigations are serology, imaging by transthoracic echocardiography and computed tomography. The authors report a case of hydatid cyst of the interventricular septum in which transthoracic echocardiography (the key investigation in all cases of hydatid cyst) computed tomography and nuclear magnetic resonance imaging (MRI) was contributive to the diagnosis. Computerized tomography scan (CT-scan) investigation also aided in the diagnosis of secondary localization of the hydatid cyst especially in the lungs and brain tissues. Diagnostic or therapeutic delay can lead to severe and even fatal complications.
