The hydatid cyst of the diaphragm is defined by the development of a hydatid cyst in the thickness of the diaphragmatic muscle. This exceptional location, even in endemic countries, represents only 0.6 to 1.5% of all hydatid localizations. It poses topographic diagnostic problems with the pulmonary and sub diaphragmatic seat despite the contribution of ultrasonography and CT scan. The treatment is mainly surgical. The prognosis is generally good apart from the risk of recurrence. We report four observations of diaphragmatic hydatid cyst collected at the Respiratory Diseases Department of the Ibn Rochd University Hospital of Casablanca. They were two women and two men. The average age was 46.5 years. All of our patients were of rural origin. One patient was already operated on for hepatic hydatic cyst 11 years ago. Surgery was recommended in all four patients, combined with medical treatment. Intraoperative exploration had found an isolated diaphragmatic hydatid cyst in four cases, fistulized in the bronchi in two cases and ruptured in the pleural cavity in one case. The evolution was good after adequate care.
