title: [Hydatid pulmonary embolisms. Seven cases].
abstract: Hydatid pulmonary embolism is a rare condition. Diagnosis is difficult and there is no consensus on treatment. Prognosis is generally poor. We conducted a retrospective analysis of patients hospitalized between 1994 and 2002 who had a diagnosis of hydatid pulmonary embolism. Seven cases were identified. All patients had a cyst which spontaneously ruptured into the bloodstream. All patients were symptomatic. Chest x-ray revealed images of metastatic pulmonary echinococciasis in all patients. Thoracic CT and/or angioscan provided the diagnosis in five patients. In one, the diagnosis was established with pulmonary angiography. For one other, the diagnosis was established at the pathology examination of the surgical specimen. Searching for the primary localization of the hydatid disease revealed hepatic cysts in all patients, associated in one with a cyst in the right atrium. The cardiac cyst was not operated and all hepatic cysts were removed. Embolectomy was performed in one patient. Medical treatment with albendazole was given in five patients. The clinical course was marked by death in two patients, due to abundant hemoptysia. The five other patients are followed regularly and were doing well at six months to five years. The diagnosis of hydatid pulmonary embolisms is basically obtained with imaging. Treatment is surgical resection of the embologenic focus then embolectomy. The role of medical treatment is not clearly defined. The short- and mid-term prognosis is generally poor.
