摘　　要：目的研究原发性肺淋巴瘤的影像诊断。方法7例均经病理和临床证实的原发性肺非何杰金淋巴瘤,均作X线胸片、腹部B超检查,其中5例作胸部CT。结果6例单发和1例多发性结节(两肺各一灶)或肿块,病变分布无肺叶偏向。病灶密度较低而不均。6个病灶边缘毛糙不规则,1个病灶边缘光整,另一个病灶边缘部分光整。其中2个病灶边缘分叶,2个病灶见长短毛刺。1个病灶见空洞。作胸部CT的5例均见空气支气管征。其中1例伴纵隔淋巴结肿大。5例合并肺叶或肺段的肺不张或部分肺不张。3例侵犯胸壁伴少量胸水。结论原发性肺淋巴瘤的影像表现多样,非特异性。常见有空气支气管征的边缘毛糙的结节或肿块。本病应与肺癌、隐源性机化性肺炎鉴别。最后定性诊断需病理检验证实。Objective To study the radiographic findings in the diagnosis of primary pulmonary lymphoma (PPL).Methods Seven patients with pathologically and clinically proved non- Hodgkin's PPL were examined by chest radiongraph (n=7) and CT(n=5). Results Single (n=6) and multiple (n=1) nodules or masses were observed in 7 patients.The distribution of lesion was no lobar tendency and density of lesion was lower and heterogeneous.6 of 8 foci were irregular and shaggy margins in 7 patients,one was well defined margin,another partly well defined margin.Borders of lobulation and spiculation were seen in 2 foci respectively.One focus showed cavitation.Air- bronchograms were all seen on CT in 5 patients,1 of these associated with mediastinal lymphoadenopathy on CT.5 had segmental or lobar atelectases or partial atelectases and 3 chest wall invasions with pleural effusion.Conclusion Radiographic findings of PPL were varied and nonspecific.The commonest findings were the nodules or masses with air- bronchograms and shaggy margins.The main radiological differential diagnosis of PPl were lung carcinoma and cryptogenic organizing pneumonia.The final definite diagnosis depends on pathology.
