Objective:
The aim of this study was to determine the incidence and diagnostic features of pleural manifestations of pulmonary hydatid disease.
Methodology:
Patients with pleural pathology in association with surgery for pulmonary hydatid disease over an 8-year period were evaluated.
Results:
Twenty-nine (6%) of 474 patients with histologically confirmed pulmonary hydatid disease had pleural abnormalities. The diagnosis was determined preoperatively in 22 patients and was based on radiographic, clinical, and/or serology findings. Bronchoscopic specimens were diagnostic in two of seven patients who had bronchoscopy. Five patients were not diagnosed until surgery. Radiographic abnormalities consisted of pleural thickening and/or free fluid without intrapleural rupture of the cysts in 21 patients. Eight patients had a hydropneumothorax. Sixteen patients had an exudative, uncomplicated effusion. The remaining patients had empyemas. All patients had resection of the pulmonary cysts, and 20 also underwent a pleurectomy. The mean length of hospital stay was 23 +/- 14 days. There was no hospital mortality.
Conclusion:
Pleural lesions associated with pulmonary hydatid disease are rare and have a variable radiographic appearance. In regions in which echinococcal disease is endemic, a high level of clinical suspicion is necessary for diagnosis and appropriate management of this condition.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
