Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst (often in the liver) into the venous circulation. We report a case of hydatid pulmonary embolism following rupture of a hydatic cyst in the right ventricle. Pulmonary angiography showed right pulmonary occlusion. Echocardiography, computed tomography scan and magnetic resonance imaging showed images suggesting a hydatid cyst. The patient underwent sternotomy and cardiopulmonary bypass in order to treat the heart cyst and remove the hydatic pulmonary obstruction. A concomitant lung hydatid cyst was extirpated.
Highlights
The lung is the second most commonly affected organ by hydatidosis, and the bilateral involvement is rare even in endemic regions.
Management of bilateral pulmonary hydatid cyst is controversial. Some authors recommend operating bilateral cysts in two-stage surgery, with an interval of three to four weeks between procedures.
The involvement of the psoas muscle is rare, its diagnosis is delayed as the latter is most of the time asymptomatic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
