肺淋巴瘤的CT与X线表现

CT Study of Pulmonary Lymphoma: Comparison with X ray

目的：回顾性分析肺淋巴瘤的ＣＴ与Ｘ线表现，以提高对肺淋巴瘤影像学表现的认识。材料与方法：２１例肺淋巴瘤均经肺或浅表淋巴结穿刺活检或手术证实。常规及薄层ＣＴ扫描并摄胸部Ｘ线正侧位片作对照检查。结果：肺淋巴瘤的影像异常可分为：肿块结节型、实变型、肺炎肺泡型、支气管血管淋巴管型、血行播散型、心包及胸膜病变型。绝大多数病例有两种或两种以上上述类型的影像表现，同时伴有纵隔肺门的淋巴结肿大。ＣＴ对其特征性表现的显示率明显高于Ｘ线，尤以薄层ＣＴ更佳。结论：多发结节伴支气管充气征和支气管周围多发小结节勾画出支气管气像是肺淋巴瘤的特征性表现；多种表现的同时出现是肺淋巴瘤的又一特点。ＣＴ检查较Ｘ线灵敏，可准确显示肺内肺外情况。

Objective: To study retrospectively CT finding and X ray features of pulmonary lymphoma and to improve its recognition.Materials and Methods:21 cases of pulmonary lymphoma, confirmed by lung histologic biopsy or clinical diagnosis with superficial lymph node biopsy. All patients were undergone chest film and CT.Results:The features of pulmonary lymphoma are classified: Masses or nodules, consolidation, infiltration, bronchiovascular and lymphatic forms pericardiac and pleural; patients have two or more types of features with lymphadenopathy of the hilar and mediastinal. CT, expecially thin section CT can reveal more typical than X ray.Conclusions: Peribronchial multiple nodules and subsequent bronchograms was the characteristical sign of pulmonary lymphoma. Multipletypes presented was also suggestive. CT is more sensitive than X ray, can accurately demontstrate conditions about intra and extra pulmonary, and was helpful to diagnosis and staging.
