Abstract

An extra-intestinal infestation of (pinworm) is uncommon. We present a case of hepatic infestation of pinworm in a 57-year-old woman, misdiagnosed as a colorectal adenocarcinoma metastasis. The route of migration from the intestine to the liver is not well established but the most plausible route seems to be hematogenous. In concordance with previously published cases, the hepatic pinworm infestation is usually localised superficially in the right liver lobe. Hence solitary lesions in this location detected radiologically should be interpreted carefully. Additionally, the serum CEA level could be useful to distinguish pinworm from malignancy.

摘要

蛲虫的肠外感染并不常见。我们报告一例57岁女性的肝脏蛲虫感染病例，该病例最初被误诊为结肠腺癌转移。蛲虫从肠道迁移至肝脏的途径尚未完全明确，但最可能的途径似乎是血行转移。与先前发表的病例一致，肝脏蛲虫感染通常位于右肝叶浅表部位。因此，对于影像学检查发现的该部位孤立性病变，应进行仔细解读。此外，血清癌胚抗原（CEA）水平可能有助于鉴别蛲虫感染与恶性肿瘤。
