目的：讨论血液病主要胸部Ｘ线表现及病理基础，不同病程及化疗后的Ｘ线变化。方法：２２例血液病患者，其中白血病１７例，恶性组织细胞病３例，恶性淋巴瘤２例，均经骨穿或临床病理证实，摄取不同病程及化疗后不同时期的胸部Ｘ线正、侧位片进行分析。结果：１．血液病的胸部Ｘ线表现大多数为片状影，其次为纵隔及肺门淋巴结肿大；２．血液病患者出现典型临床症状或早期及时确诊２个月后，肺部才可能出现浸润征象；３．肺部浸润病灶化疗２～３周，近１／３患者好转或吸收，化疗１月者，有效率达６０％以上。结论：血液病的胸部Ｘ线表现无特征性，不同病程及化疗后Ｘ线变化复杂，必须结合病史，随诊观察才能确诊。
Objective: To discuss the main chest X-ray manifestations of blood diseases and pathological basis, different course and X-ray changes after chemotherapy.
