Pulmonale Echinokokkose
摘要
Echinococcosis is a tapeworm larval infection with two disease entities that fundamentally differ in terms of epidemiology and clinical management. Cystic echinococcosis (CE, dog tapeworm, Echinococcus granulosus sensu lato) is always imported into Germany, while alveolar echinococcosis (AE, fox tapeworm, Echinococcus multilocularis) is endemic in this country. Liver involvement is common but pulmonary manifestations are also possible, particularly in the case of CE.
Aim of the studyThe epidemiology, clinical features, diagnostics and treatment of pulmonary echinococcosis are presented, focusing on clinically relevant differences between CE and AE.
Material and methodsA narrative search was carried out in PubMed (up to June 2025), supplemented by guidelines, national reporting data and expert clinical experience. A selection of relevant original papers, reviews and registry studies is presented.
ResultsPulmonary echinococcosis is nearly always CE. Pulmonary AE is rare and almost always secondary to advanced liver involvement. The diagnosis is based on imaging and two-stage serology. The CE cysts grow expansively, can rupture and appear on computed tomography (CT) as solitary, hypodense cavities with clearly recognizable walls. The AE presents with multiple, irregularly margined, metastasis-like focal lesions. The CE is primarily treated with curative surgery followed by short-term treatment with benzimidazoles, whereas AE usually requires long-term benzimidazole treatment as curative resection is not possible in most cases.
DiscussionIncreasing migration (in the case of CE) and growing fox populations (in AE) suggest that case numbers will rise. Therefore, the diseases should be considered in the differential diagnosis of unclear pulmonary lesions, especially in patients with appropriate sociodemographic characteristics.
