摘要
目的 提高对原发性肺非霍奇金恶性淋巴瘤影像学表现的认识。方法 3例经病理、临床证实的原发性肺非霍奇金恶性淋巴瘤 ,结合文献对其影像学 (胸部CT及X线片 )特征及病理进行分析讨论。结果 3例患者均经CT导引肺穿刺切割肺活检获得标本并最终获得病理和免疫组织化学诊断 ,所有 3例在胸片和CT上存在着不同范围的肺实变 ,在所有实变病灶中见空气支气管征。其中 1例除了多个肺叶的实变外 ,在右下肺有一大小为 3.5cm× 3.0cm的肿块 ,在其它肺叶还有多个大小不等的结节 ,并且在肿块及部分结节中见空气支气管征。毛玻璃样改变或间质结构增厚所致的网格条索样改变在大多数肿块、结节和实变的边缘或其它部位存在。所有病灶中无坏死、空洞及钙化存在。无胸膜增厚及胸液。无明显的肺门及纵隔淋巴结肿大。结论 原发性肺非霍奇金恶性淋巴瘤影像学表现具有一定的特征 ,影像学表现有助于该疾病的诊断。经皮穿刺肺活检可有效的获得病理结果。
Objective To describe the radiographic and CT findings of primary pulmonary non-Hodgkin lymphoma(PPL),and to evaluate percutanous transthoracic needle biopsy(PTNB) in the diagnosis of PPL. Methods Chest radiographs and CT scans of three patients with histologically proven PPL were reviewed. The diagnosis of PPL was confirmed histologically with specimens obtained by means of PTNB. Results Consolidation with air bronchograms on the chest X-ray films and CT scans was found in all cases. Multiple ill-defined nodules of various size in both lungs and a mass with air bronchogram in the right lower lobe on the CT scan were present in one case. Ground-glass opacity or reticular lesions were present in both lung fields. Hilar/mediastinal adenopathy and pericardial/pleural effusion were not features of these cases. PTNB was diagnostic in all three cases. No complications occurred during these procedures. Conclusions PPL has some specific imaging features. Radiographic and CT findings are helpful in the diagnosis of primary pulmonary malignant lymphoma. A specific diagnosis can be obtained by means of PTNB.
