This case report presents a 43-year-old worker (welder in the locksmith trade) from Bosnia and Herzegovina who was diagnosed with advanced hydatidosis during a preventive medical examination. The patient had a history of frequent close contact with dogs at home and at work and reported a long-standing sensation of heaviness in the left side of his abdomen. As part of his routine occupational health examination, he had a complete laboratory testing, abdominal ultrasound, multislice computed tomography (MSCT), and a consultation with an infectious disease specialist and abdominal surgeon. Imaging revealed multiple cystic formations in the left hemiabdomen and a cyst in segment VIII of the liver, confirming the diagnosis of multivisceral echinococcosis. The patient was promptly treated with preoperative (and postoperative) albendazole to reduce the cyst size and prevent complications. This case highlights the critical role of ultrasound in the diagnosis of hydatidosis, especially in an occupational medicine context. As part of preventive screening, ultrasound is a valuable tool for the early detection of echinococcosis in workers in high-risk environments. Early diagnosis allows for timely intervention, reducing the risk of disease progression to an advanced stage. This case underscores the importance of implementing effective epidemiological strategies, including regular screenings and awareness campaigns, in order to control the spread of echinococcosis in endemic regions.

该病例报告介绍了一名来自波黑的43岁工人（锁匠行业的焊工），在一次预防性体检中被诊断出患有晚期囊尾蚴病。患者有在家和工作场所频繁接触狗的历史，并且长期感到左腹部沉重。作为其常规职业健康检查的一部分，他进行了完整的实验室检测、腹部超声波检查、多层计算机断层扫描（MSCT）以及传染病专家和腹腔外科医生的咨询。影像学检查发现左侧半腹有多发囊肿，在肝脏VIII段有一个囊肿，确诊为多器官囊尾蚴病。患者在接受术前（及术后）阿苯达唑治疗以缩小囊肿并预防并发症后得到及时治疗。该病例强调了超声波在诊断囊尾蚴病中的关键作用，尤其是在职业医学领域。作为预防性筛查的一部分，超声波是早期发现工作环境高风险工人中囊尾蚴病的宝贵工具。早期诊断有助于及时干预，减少疾病进展到晚期阶段的风险。该案例突显了实施有效的流行病学策略的重要性，包括定期检查和宣传活动，以控制疫区内的囊尾蚴病传播。
