【摘要】目的:提高纵隔巨淋巴结增生症的认识水平,探讨纵隔巨淋巴结增生症的影像学表现及诊断价值。方法:通过四例手术及病理证实的巨淋巴结增生症的病例分析以及文献资料复习,对本病的影像学诊断与鉴别诊断进行讨论。结果:巨淋巴结增生症是一种异源性的罕见的淋巴组织增生性良性疾病,[1]其组织形态:可分为透明血管型和浆细胞型,前者多见,常表现为纵隔病变,后者好发于腹膜后和肠系膜、颈部、盆腔等。增强后有不同程度强化,透明血管型成中等明显强化,浆细胞型呈现轻度强化。结论:巨淋巴结增生症具有特征性影像学表现,CT具有较高诊断价值,在动脉期明显强化,延迟期特强化,提示淋巴结增生症病的诊断。

【Abstract】Objective: to improve mediastinal giant lymph node hyperplasia, discusses the understanding level mediastinal giant lymph node hyperplasia of imaging manifestations and diagnostic value.Methods: through the four cases of surgery and pathology confirmed cases of giant lymph node hyperplasia and literature review and analysis of the imaging diagnosis and differential diagnosis is discussed.Results: the giant lymph node hyperplasia is a vision of the rare odontogenic lymphoid tissue proliferative benign disease, the organization forms: can be divided into transparent vessels and plasma cells, the former, often for primary lesions, the latter in retroperitoneal and mesenteric, neck, pelvic etc ......
