Hepatic artery aneurysms (HAA) are rare and may be seen in the setting of infection and vascular disease. Clinical presentation is variable but many are found incidentally during imaging studies. The association of HAA with focal nodular hyperplasia (FNH) is rarely reported in literature. We present the case of a 68-year-old woman found to have a hepatic artery aneurysm and hepatic mass, both within the same liver segment. FNH and hepatic adenomas share similar imaging features but have different treatments due to malignant potential of the latter, and biopsy should be performed when adenoma cannot be excluded. In this case biopsy of the mass revealed it to be FNH and the aneurysm was treated with embolization rather than surgery.
肝动脉瘤（HAA）较为罕见，可在感染和血管疾病的情况下出现。临床表现多样，但许多是在影像学检查时偶然发现的。HAA与局灶性结节性增生（FNH）的关联在文献中鲜有报道。我们报告一例68岁女性病例，该患者在同一肝段内同时发现肝动脉瘤和肝脏肿块。FNH和肝腺瘤具有相似的影像学特征，但由于后者具有恶性潜能，治疗方式不同，当不能排除腺瘤时应进行活检。在本病例中，肿块活检显示为FNH，动脉瘤采用栓塞而非手术治疗。
