* * Nodular sclerosing Hodgkin disease in a 38-year-old man. The patient had undergone treatment 4 years earlier and was in complete remission. CT scan shows bilateral ill-defined lung masses with a nodular lesion in the left lung 。There was no mediastinal adenopathy. * * Nodular sclerosing Hodgkin disease in a 19-year-old woman. The patient had undergone treatment 18 months earlier and was in complete remission. CT scan shows recurrent pulmonary disease with an ill-defined nodular lesion in the right lung (arrow). Mediastinal adenopathy is also seen (arrowheads). * * Mixed-cellularity Hodgkin disease in a 25-year-old man The patient had undergone treatment 3 years earlier and was in complete remission. chest radiographs demonstrate disseminated micronodular disease predominantly involving the left lung. A pulmonary consolidation in the left inferior lobe and a left pleural effusion are also seen. CT scan shows bilateral ill-defined peribronchial micronodular lesions less than 1 cm in diameter. * * 肺继发性淋巴瘤2例 * * 1:弥漫型大B细胞NHL 2:弥漫型大T细胞NHL * * Nodular sclerosing Hodgkin disease in a 31-year-old man Anteroposterior chest radiograph shows an ill-defined, right-sided hilar and mediastinal mass. CT scan demonstrates a pulmonary consolidation with an air bronchogram. There is typical micronodulation along the bronchi. The patient underwent bronchoscopy, which demonstrated an endobronchial lesion due to Hodgkin disease. * * 3个病例 * * 2个病例 * * AIDS相关的肺淋巴瘤(pulmonary lymphoma) AIDS患者，有发热、咳血症状。? X线表现：双肺实质多发结节状、团块状实性肿块影。 CT表现：双肺多发类圆形实性肿块，所有肺叶均有受累，病变主要分布在肺外围；肺窗示病变边界不清楚，周围可见磨玻璃影；纵隔窗示病变呈软组织密度，局部可见含气支气管影；双侧胸腔有少量积液。? 诊断：肺恶性淋巴瘤（弥漫性大B细胞型）。 * * * * * 肺淋巴瘤的影像诊断 唐光才 教授 泸州医学院附属医院放射科 * * 原发性结外淋巴瘤 （Primary Extranoduallymphoma） 定义：原发性结外淋巴瘤(PENL)是指淋巴瘤主体病变在结外器官或者组织，伴或者不伴有区域淋巴结的侵润（结外病灶75％ ，结内病灶25％） 。 发生部位：可发生于结外的任何器官、组织，如胃肠道、中枢、鼻咽、头颈部、肺、腹腔、腹膜后、泌尿生殖系等。 临床表现：临床表现缺乏特异性。 病理改变：绝大多数结外淋巴瘤为非何杰金氏。 Freeman C,et al.
