Abstract:
This report presented the first imported case of alveolar echinococcosis in Tianzhu Tibetan Autonomous County, Gansu Province. The patient was a local resident who had worked in Hotan Prefecture, Xinjiang Uygur Autonomous Region from 2019 to 2023, an area co-endemic for cystic and alveolar echinococcosis. He presented with hepatic discomfort in June 2023. Imaging examinations revealed an 8 cm × 6 cm mass in the left liver lobe, and serological testing showed positive IgG antibodies against Echinococcus. Post-surgical pathology confirmed the diagnosis of alveolar echinococcosis. Given that Tianzhu County has historically been endemic only for cystic echinococcosis and has not reported local cases of alveolar echinococcosis, this case was identified as an imported case based on epidemiological history. The case underwent left lateral hepatic lobectomy and no recurrence was seen at 2-year follow-up post-surgery. It is recommended to enhance the identification of different types of echinococcosis among clinicians, improve health education among migrant laborers, reinforce active screening among returning labors, and advance a One Health concept-based, cross-regional “human-animal-environment” joint prevention and control mechanism to prevent the risk of imported echinococcosis.
