Hydatid disease is a parasitic zoonosis caused by Echinococcus granulosus, typically transmitted through contact with infected dogs or ingestion of contaminated food. Although the liver and lungs are the most commonly affected organs, mediastinal localization is extremely rare and presents diagnostic and therapeutic challenges. This report describes the case of a 48-year-old man with a history of hepatic and pulmonary hydatid disease who developed a retrocardiac mediastinal hydatid cyst (HC). The patient presented with cough, dyspnea, and back pain. Imaging (computed tomography (CT) and magnetic resonance imaging (MRI)) revealed a 9.3 × 7.0 cm cyst compressing mediastinal structures, including the atria and aorta. Surgical removal via posterolateral thoracotomy was performed successfully, and the patient recovered without complications. Albendazole was administered to the patient over a six-month period as part of the postoperative antiparasitic treatment. Echinococcus granulosus causes HCs, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. HC is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease. Cystic echinococcosis is the most common human disease of this genus, and it accounts for a significant number of cases worldwide. Imaging plays a key role in diagnosis and surgical planning, while surgery remains the mainstay of treatment, supported by medical therapy.
包虫病是一种由细粒棘球绦虫引起的寄生虫人畜共患病，通常通过接触受感染的狗或摄入受污染的食物传播。虽然肝脏和肺是最常受影响的器官，但纵隔定位极为罕见，在诊断和治疗上具有挑战性。本报告描述了一名48岁男性的病例，该患者有肝和肺包虫病病史，后来出现了心后纵隔包虫囊肿（HC）。患者表现为咳嗽、呼吸困难和背痛。影像学检查（计算机断层扫描（CT）和磁共振成像（MRI））显示一个9.3×7.0厘米的囊肿压迫纵隔结构，包括心房和主动脉。通过后外侧开胸手术成功切除囊肿，患者康复且无并发症。作为术后抗寄生虫治疗的一部分，患者接受了为期六个月的阿苯达唑治疗。细粒棘球绦虫可引发包虫囊肿，这是一种严重的人畜共患和肺部寄生虫病，可模仿各种病症，且往往比疾病本身更难处理。在印度、伊朗、中国和地中海国家，包虫囊肿被视为一个重大的健康问题，这些国家缺乏令人满意的环境卫生、预防医学和兽医服务。棘球蚴病在一些国家仍然是主要的社区健康负担，在某些地区，它构成一种新出现和再次出现的疾病。囊性棘球蚴病是该属最常见的人类疾病，在全球范围内导致大量病例。影像学在诊断和手术规划中起关键作用，而手术仍然是主要的治疗手段，并辅以药物治疗。
