[Intrathoracic hydatid cyst. Contribution of tomodensitometry. Apropos of 25 cases].

Twenty-five cases of thoracic hydatic disease, studied by CT since 1982, are reviewed. Fifteen patients were Maghrebin, 10 were native. The lungs were interested 22 times, the mediastinum 3 times and the heart only once. Complications of hydatic disease were present 8 times. We compare contribution of CT to the other diagnosis criterious. Our results show the accuracy of CT for the diagnosis of non complicated cyst and the lack of specificity for complicated cysts.
