[Imaging of hydatid cyst of the lung]

The pulmonary hydatid cyst is frequent in Mediterranean countries such as Morocco. Our analytic study concerned 70 cases of lung hydatid cysts collected from 2007 to 2010. Mean age was 35years and we noted a male predominance (53%). Forty-seven percent of patients belong to rural environment where 64% of them were in contact with dogs. The respiratory symptomatology was made mostly by cough (86%) and chest pain (70%). Diagnosis was based on radioclinical arguments with positive hydatic serology in some cases. The cyst was single in 84% of the cases, safe in 55% of the cases. The location in the right lung was dominant with a major affection of the right lower lobe. Conventional surgery was indicated in 67 cases. The liver hydatid cyst was discovered in 20% of cases and treated at the same time phases in 71% of cases. The evolution was good in 73% of the cases and marked by a recurrence in three of the operated cases.
