[Coinfection with hydatid cyst and pulmonary tuberculosis].

Morocco is an endemic area for both hydatid cyst and tuberculosis (TB). The co-occurrence of these two diseases in lung is unusual, especially when localized in the same area. We describe the case of a patient with pulmonary hydatid cyst associated with tuberculosis infection where the diagnosis was unknown prior to surgery because TB tests were negative. The surgical resection was very difficult because of inflammation in the surrounding tissue and its fragility. However, the postoperative course was uneventful. The goal of this case report is to keep in mind that such co-infection is possible especially in endemic countries.
