Fatal Outcome of Ruptured Pulmonary Hydatid Cyst.

: Most authors believe that the optimal treatment for pulmonary hydatid cyst is surgery. Albendazole has been used as a prophylactic measure for reducing recurrence rate but there are some controversies about this strategy. Some researchers have described the increased risk of spontaneous rupture of cysts following albendazole treatment. In this case report, we present a case of spontaneous rupture of pulmonary hydatid cyst with fatal outcome that may be the adverse cause of albendazole.
