摘　　要：目的总结分析肺结节性淋巴组织增生(PNLH)的临床和影像表现并分析其病理特征。方法回顾性分析9例PNLH患者的临床及影像表现。结果9例PNLH患者中5例为偶然发现,4例因胸部症状就诊,实验室检查无特异性,病灶均位于胸膜下,可见邻近胸膜凹陷,病灶以实性居多,可有毛刺和棘状突起,其内偶可见低密度区及空泡,增强扫描呈明显强化,但多数不伴有肺门或纵隔淋巴结肿大,未见胸腔积液。结论PNLH的临床表现无特征性,影像表现和肺恶性肿瘤有较多重叠,确诊需依靠病理检查。Objective To summarize and analyze the clinical and imaging features of pulmonary nodular lymphoid hyperplasia(PNLH)and its pathological features.Methods The clinical and imaging features of PNLH in 9 patients were analyzed retrospectively.Results Of the 9 patients with PNLH,5 were found incidentally while other 4 presented with chest symptoms.Laboratory tests showed no specificity,and the lesions were located under the pleura with adjacent pleural indentation.Most lesions were solid with spiculation sign or spiculate protuberance.Hypodense area and vocule were visible within some lesions.Enhanced scan showed the lesion with marked enhancement,however most did not had lymph node enlargement and pleural effusion.Conclusion The clinical manifestations of PNLH are non-specific,and the imaging characteristics overlap with those of malignant lung tumors.Thus the diagnosis of PNLH relies on the pathological examination.
