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.
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.
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.
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.
描述原发性肺非霍奇金淋巴瘤（PPL）的影像学及CT表现，并评估经皮经胸针吸活检（PTNB）在PPL诊断中的作用。
回顾3例经组织学证实的PPL患者的胸部X线片及CT扫描结果。通过PTNB获取标本，经组织学确诊为PPL。
所有病例胸部X线片及CT扫描均显示实变伴空气支气管征。1例CT扫描显示双肺多发大小不一、边界不清的结节及右下叶一伴有空气支气管征的肿块。两肺野均可见磨玻璃影或网状病变。这些病例均无肺门/纵隔淋巴结肿大及心包/胸腔积液表现。3例PTNB均具有诊断价值。操作过程中未发生并发症。
PPL具有一些特定的影像学特征。影像学及CT表现有助于原发性肺恶性淋巴瘤的诊断。通过PTNB可获得明确诊断。
