  • Clinicopathological Analysis of Hepatic Angiomyolipoma

    【摘要】目的探讨肝血管平滑肌脂肪瘤的临床病理特点、诊断及鉴别诊断。 方法对3例肝血管平滑肌脂肪瘤患者有关病理检查结果进行回顾性分析。 结果肿瘤位于肝右叶2例,肝左叶1例。肿瘤直径为2~10 cm,平均6.2 cm。3例肿瘤内均见平滑肌、脂肪、畸形厚壁血管,但未见髓外造血灶。对黑色素瘤(HMB45)、结合蛋白(desmin)及肌动蛋白(actin)检查均呈阳性反应。术后随访6~36个月,未见肿瘤复发。结论肝血管平滑肌脂肪瘤由3种成分组成,病理形态变化多样,必须与多种肝肿瘤相鉴别。平滑肌细胞HMB45表达呈强阳性反应是诊断肝血管平滑肌脂肪瘤较可靠的依据。

  • 18 例少见肝占位性疾病的诊治分析

    目的 总结少见肝占位性病变的诊治体会。 方法 回顾性分析 2009 年 6 月至 2016 年 4 月期间遵义医学院附属医院收治的 18 例少见肝占位性病变患者的临床资料。 结果 18 例患者中,包括肝结核 4 例,肝血管平滑肌脂肪瘤(HAML) 3 例,肝局灶性结节性增生(FNH) 4 例,肝腺瘤 1 例,肝寄生虫病 6 例,所有患者的影像学图像均表现为肝占位性病变。4 例肝结核患者经正规抗结核治疗好转出院;2 例肝肺吸虫病患者接受吡奎酮正规驱虫治疗,随访期间无异常;1 例血吸虫病患者行手术治疗后治愈出院,未获得随访;3 例寄生虫感染患者行手术切除病变部位,随访期间无异常;3 例 HAML 患者行手术治疗,随访期间病情无明显异常,4 例 FNH 患者行手术治疗,2 例随访期间未见明显异常,2 例未获得随访;1 例肝腺瘤患者行手术治疗,随访无明显异常。出院后 15 例患者获访,随访时间 2~6 个月,中位数为 3.5 个月。随访期间,除 4 例肝结核患者因抗结核治疗引起相应并发症、经保守治疗好转外,其余患者均未见明显并发症发生。 结论 大多数少见肝占位性病变术前诊断较困难,熟悉掌握疾病相关特点及影像学表现,可降低误诊率,但明确诊断主要依靠病理学检查,治疗以手术为主。

  • Typical imaging features of hepatic angiomyolipoma: “rapid wash-in and wash-out”, but not hepatocellular carcinoma

    Hepatic angiomyolipoma (HAML) is a rare benign mesenchymal tumor of the liver, which has highly variable imaging appearances, often leads to missed diagnosis and misdiagnosis. The images of 2 patients with HAML confirmed by pathology were presented in this study, and the typical imaging features of the HAML, the underlying pathophysiological mechanism, and the differential diagnosis were briefly summarized so as to deepen the understanding of HAML and to improve the diagnosis and differential diagnosis abilities of HAML, then reduce the rates of missed diagnosis and misdiagnosis of the HAML.
