Toxocariasis is an uncommon cause of multiple cavitary lung lesions and an ill-defined liver lesion. We herein report a patient with lung and liver toxocariasis, which mimicked metastatic lesions of colon cancer on F-FDG PET-CT and chest and abdominal CT performed for cancer staging after diagnosis of colon cancer. The patient was diagnosed with lung and liver toxocariasis by a positive enzyme-linked immunosorbent assay. Lung toxocariasis may occur as multiple cavitary lung lesions, and liver toxocariasis may appear as a solitary ill-defined nodule, which may be misdiagnosed as metastatic tumors. Clinicians should consider toxocariasis when multiple cavitary lung lesions and a solitary ill-defined focal liver lesion are detected, especially in a patient with cancer.
弓蛔虫病是导致肺部出现多个空洞性病变以及肝脏出现边界不清病变的罕见病因。我们在此报告一例患有肺部和肝脏弓蛔虫病的患者，在结肠癌诊断后进行的F-FDG PET-CT以及胸部和腹部CT检查中，其病变酷似结肠癌的转移灶。该患者通过酶联免疫吸附试验呈阳性而被诊断为肺部和肝脏弓蛔虫病。肺部弓蛔虫病可能表现为多个空洞性肺部病变，而肝脏弓蛔虫病可能表现为单个边界不清的结节，这可能会被误诊为转移性肿瘤。当检测到肺部有多个空洞性病变以及肝脏有单个边界不清的局灶性病变时，临床医生应考虑弓蛔虫病，尤其是在癌症患者中。
