Capillaria hepatica (syn. Calodium hepaticum) is a parasitic nematode of rodents, rarely infecting humans. An asymptomatic Israeli adult male with extensive travel history was diagnosed with a liver mass on routine post-thymectomy follow-up. Imaging and computer tomography (CT) guided biopsy were inconclusive. Surgical excision revealed an eosinophilic granuloma with fragments of a nematode suspected to be C. hepatica. Molecular methods verified the diagnosis, and the patient was treated empirically. This is the first case of hepatic capillariasis described in Israel, and the first to be diagnosed using molecular methods.
肝毛细线虫（又名肝毛细线虫）是一种寄生在啮齿动物体内的线虫，很少感染人类。一名无明显症状的、有广泛旅行史的以色列成年男性，在常规的胸腺瘤切除术后随访中被诊断出患有肝脏肿块。影像学和计算机断层扫描（CT）引导下的活检结果不确定。手术切除显示为嗜酸性肉芽肿，其中有疑似肝毛细线虫的线虫片段。分子方法证实了诊断，患者接受了经验性治疗。这是在以色列首次描述的肝毛细线虫病病例，也是首例使用分子方法诊断的病例。
