Cystic echinococcosis is non-endemic in Denmark and primarily diagnosed in migrants from endemic areas. Here, we report a case of pulmonary cystic echinococcosis in a Danish woman with no history of longer-term stays abroad, only holiday travelling to tourist destinations. This is the first case reported in international literature from Denmark where the causative parasite was identified to species and genotype level.
A 27-year-old pregnant Danish woman was admitted for examination because of haemoptysis for three months.Chest X-ray and computed tomography revealed a cystic structure in the left lung and a left-sided thoracotomy was performed to remove the cyst. Postoperative histopathological examination revealed a hyaline membrane and protoscoleces. Subsequently, infection with was confirmed by molecular methods. The causative agent was further characterised as G1, which is not known to have an established life cycle in Denmark. It was concluded that the infection was most likely acquired during a tourist travel to an endemic country. The patient was treated with albendazole for four weeks.
This case of pulmonary cystic echinococcosis in a person who had lived in Denmark and had history of only short-term tourist travelling abroad highlights that the disease may be acquired during tourist travelling. Thus, a diagnosis of cystic echinococcosis should be considered not only in migrants from endemic countries but also in travellers upon incidental findings of a lung or liver cysts. The case also exemplifies the importance of reaching a diagnosis at species and genotype level.
囊性棘球蚴病在丹麦并非地方性疾病，主要在来自流行地区的移民中被诊断出来。在此，我们报告一例丹麦女性的肺囊性棘球蚴病病例，该女性无长期国外居住史，仅有前往旅游目的地的度假旅行经历。这是丹麦国际文献中报道的首例病因寄生虫被鉴定到物种和基因型水平的病例。
一名27岁的丹麦孕妇因咯血三个月入院检查。胸部X线和计算机断层扫描显示左肺有一个囊性结构，遂进行左侧开胸手术以切除囊肿。术后组织病理学检查发现有透明膜和原头节。随后，通过分子方法确诊感染。病原体进一步被鉴定为G1型，在丹麦尚未发现其有既定的生命周期。结论是感染很可能是在前往流行国家的旅游期间获得的。患者接受了四周的阿苯达唑治疗。
该例居住在丹麦且仅有短期国外旅游史的肺囊性棘球蚴病病例表明，这种疾病可能在旅游期间感染。因此，不仅应在来自流行国家的移民中考虑囊性棘球蚴病的诊断，在偶然发现肺或肝囊肿的旅行者中也应考虑。该病例还例证了在物种和基因型水平进行诊断的重要性。
