Bilateral hydatid cyst of pulmonary arteries: MR and CT findings.
The location of hydatid cysts inside pulmonary arteries has been reported only on rare occasions in the literature and is caused, in the majority of cases, by embolization due to the rupture of hydatid cysts located in the heart; more rarely, hematogenous dissemination from a hepatic focus is the cause. We report a case of a 44-year-old patient with hydatid cysts located in both the right and left pulmonary arteries, whose first clinical reference was hemoptysis. The patient had undergone surgery because of a hepatic hydatid cyst 5 months previously. The importance of this case lies in the infrequent bilateral location in both pulmonary arteries and in the absence of intracardiac hydatid cysts.
