摘　　要：目的报道1例以多发肺、肝结节为临床表现的IgG_(4)相关性肝脏炎性假瘤(HIPT)合并肝组织感染患者的临床影像特点并复习文献,以期帮助临床医师诊治及鉴别IgG_(4)相关性肝脏炎性假瘤。方法回顾性分析1例多发肺、肝结节的IgG_(4)相关性疾病(IgG_(4)-RD)患者的病例资料,并通过检索中英文数据库,综合文献结果,总结IgG_(4)相关性HIPT和肝组织感染的临床影像特点。结果本例为64岁女性,因“纳差乏力1年余、干咳4个月”至解放军总医院第一医学中心风湿免疫科住院,仅有肺、肝多发结节,无眼睑、腮腺、颌下腺、胰腺等受累,血IgG_(4)(14.1 g/L)及C反应蛋白(CRP,82.1 mg/L)水平均升高。肺CT提示双肺多发实性结节、边界清楚。腹部增强磁共振检查显示肝S7段结节,周围有假包膜,边界清楚,均匀强化;肝S5段结节,边界模糊,环形强化;最终肝结节通过病理和病原学宏基因测序证实S7段结节为IgG_(4)相关性HIPT,S5段结节为肝组织感染。经足疗程抗感染和甲泼尼龙、来氟米特治疗后,复查肺、肝结节基本消失。检索中国知网、万方数据知识服务平台、PubMed数据库(截至2023年9月),未见IgG_(4)-RD肝脏受累同时合并感染的病例报道。目前共报道26例IgG_(4)-RD肝脏受累病例,男性居多(92.3%),平均年龄51岁,多以肝功能异常为首发症状就诊,血炎症指标正常,影像表现以单个结节多见(88.5%),边界清楚,均匀强化和环形强化均可见,常同时合并胰腺、胆道受累,病理为确诊该疾病的金标准。结论本例肝内多发结节为IgG_(4)相关性HIPT与感染共存。在诊治以肝多发结节为表现的IgG_(4)-RD患者时,若结节影像学特征不一致,需考虑原发病与其他情况并存的情况,该病容易误诊,须获取病理组织帮助确诊。Objective To report the clinical and imaging characteristics of a case with the clinical manifestation of multiple lung and liver nodules,diagnosed as IgG_(4)-related hepatic inflammatory pseudotumor(HIPT)complicated by hepatic tissue-infection,and review the literature in order to facilitate clinical diagnosis and differential identification of IgG_(4)-related HIPT.Methods A retrospective analysis was conducted on the medical records of a patient with IgG_(4)-related disease(IgG_(4)-RD)characterized by multiple lung and liver nodules.A literature review was performed by searching Chinese and English databases to summarize the clinical and imaging characteristics of IgG_(4)-related HIPT and hepatic tissue infection.Results The case involved a 64-year-old female admitted to the Rheumatology and Immunology Department of the First Medical Center of Chinese PLA General Hospital due to"poor appetite and fatigue for over a year,and dry cough for four months".She presented with multiple nodules in the lungs and liver,without involvement of the eyelids,salivary glands,submandibular glands,or pancreas.Laboratory test results revealed elevated serum IgG_(4) levels at 14.1 g/L and C-reactive protein(CRP)at 82.1 mg/L.Pulmonary CT scans indicated multiple solid nodules in both lungs with clear boundaries.Abdominal contrast-enhanced MRI revealed a nodule in liver segment S7 with a pseudocapsule around it,clear boundaries,and uniform enhancement;another nodule in liver segment S5 with blurred boundaries and ring enhancement.The final diagnosis of the liver nodules was confirmed by pathological and metagenomic sequencing to be an IgG_(4)-related HIPT in segment S7 and hepatic tissue infection in segment S5.After a full course of anti-infection and treatment with methylprednisolone and leflunomide,follow-up imaging showed near-complete resolution of the lung and liver nodules.Literatures were searched in China National Knowledge Infrastructure(CNKI),Wanfang,and PubMed databases(up to September 2023),and no case of IgG_(4)-RD comp
