Cystic echinococcosis is a widely endemic helminthic disease worldwide but occurs only rarely in Central Europe. Humans are infected as ‘aberrant’ hosts by Echinococcus granulosus and develop cysts in numerous different organs. 20%–30% of the affected individuals develop hydatid disease in the lungs with associated complications including pleuritis, lung abscess and pneumothorax. Radiologically, the pulmonary lesions of cystic echinococcosis occasionally pose difficulties in the differential diagnosis of primary lung carcinoma or metastatic disease and vice versa. Herein we report on a case of pulmonary hydatid disease in a 25-year-old Iraqi male presenting with a cystic lesion of the lung associated with thoracic pain and involuntary weight loss. Despite of its rare occurrence in Central Europe, clinicians, radiologists and pathologists should be aware of this entity and its pulmonary manifestations. During frozen section examination, imprint cytology specimens may facilitate the detection of the pathogens.

BACKGROUND It now seems that all pulmonary hamartomas (PHs) are large cystic-solid lesions that are difficult to diagnose. However, few cases of large cystic-solid PHs have been reported. The present case report presents a large cystic-solid PH and provides a literature review of the imaging features, formation mechanism and histopathological basis of PHs. CASE SUMMARY A 53-year-old woman with no clinical symptoms underwent a chest computed tomography (CT) examination at our hospital. Nonenhanced CT images revealed a large, flat tumor with multiple air-containing cysts in the left thoracic cavity and a cystic part confined to the medial side of the tumor; the solid part of the tumor showed abundant fat and lamellar soft tissue components. Multiple small blood vessels were detected in the solid part of the tumor on contrast-enhanced CT images. Given the large size of the lesion, the patient elected to undergo surgery. Histological examination revealed PH. A detailed review of the patient’s CT imaging showed that the lesion had a small vascular pedicle to the left lower lobe, which was a clue to its lung tissue histological origin. According to immunohistochemical staining, the confined multiple air-containing cysts were caused by the entrapment of respiratory/alveolar epithelium. CONCLUSION This case shows the imaging manifestations of a large PH. Heightened awareness of its formation mechanism and histopathological basis may alert radiologists to consider this diagnosis in their daily workflow.

ABSTRACT. The article presents a modern view of the diagnosis and treatment of pulmonary echinococcosis. The etiology, pathogenesis, clinical picture, ways of diagnosis and available methods of treatment of this pathology are highlighted. The purpose of the work was to acquaint doctors of various specialties with clinical cases of pulmonary echinococcosis. Two clinical cases of pulmonary echinococcosis became the object of the work. The first clinical example concerned a 17-year-old boy who had a typical course of echinococcosis and who underwent left lower lobectomy. The second clinical example concerned a young woman in whom pulmonary echinococcosis had an atypical course and was diagnosed only intraoperatively. It was concluded that the most effective method of treatment of echinococcal lung cysts is surgical operation. The volume of surgical intervention depends on many factors and is decided individually in each specific case. In the postoperative period, preventive anthelmintic therapy is mandatory.
