A 60-year-old male with acute promyelocytic leukemia demonstrated bilateral diffuse air-space consolidation on chest X-ray. An autopsy on the next day revealed pure pulmonary alveolar hemorrhage without leukemic infiltration or inflammation. Disseminated intravascular coagulation was confirmed microscopically. In severe hemorrhagic diathesis and leukopenia, it is impossible to distinguish pulmonary hemorrhage from pneumonia by X-ray alone. Bronchalveolar lavage may be the only possible diagnostic approach.
一名60岁的急性早幼粒细胞白血病男性患者，胸部X线显示双侧弥漫性气腔实变。次日尸检发现单纯肺泡出血，无白血病浸润或炎症。显微镜检查证实存在弥散性血管内凝血。在严重出血倾向和白细胞减少的情况下，仅通过X线无法区分肺出血和肺炎。支气管肺泡灌洗可能是唯一可行的诊断方法。
