Radiofrequency ablation (RFA) of a hepatic tumour is an established treatment option with an acceptable complication rate. Formation of a pseudoaneurysm after RFA of liver metastasis is an uncommon complication. We report the case of a 69-year-old female patient developing a hepatic pseudoaneurysm after RFA of liver metastasis. On a follow-up CT scan 6 weeks later, there was spontaneous resolution of the pseudoaneurysm. Hepatic pseudoaneurysms are usually treated owing to the risk of rupture. Invasive procedures or conservative management of an asymptomatic hepatic pseudoaneurysm is still the subject of debate. The spontaneous resolution of a hepatic pseudoaneurysm in our patient suggests that an asymptomatic pseudoaneurysm maybe observed for resolution instead of being treated at presentation.
肝肿瘤的射频消融术（RFA）是一种已确立的治疗选择，并发症发生率可接受。肝转移瘤射频消融术后形成假性动脉瘤是一种罕见的并发症。我们报告一例69岁女性患者，在肝转移瘤射频消融术后发生肝假性动脉瘤。6周后的随访CT扫描显示，假性动脉瘤自发消退。由于存在破裂风险，肝假性动脉瘤通常需要治疗。对于无症状肝假性动脉瘤的侵入性治疗或保守处理仍存在争议。我们患者的肝假性动脉瘤自发消退提示，对于无症状假性动脉瘤，也许可以观察其消退情况，而不是在发现时就进行治疗。
