Pulmonary Leukemic Infiltration: A Case Report

白血病肺部浸潤:案例報告

摘要


Pulmonary leukemic infiltration is usually asymptomatic, although it may present with critical clinical conditions. It is difficult to diagnose because of its non-specific radiographic patterns and laboratory findings. Therefore, invasive diagnostic procedures are usually required to reach the diagnosis. Leukostasis with leukemic alveoli migration is considered to be its characteristic pathologic finding. Here, we report a case of pulmonary leukemic infiltration requiring mechanical ventilation and extracorporeal membrane oxygenation support that was diagnosed using bronchoalveolar lavage and postmortem sono-guided lung biopsy.

白血症肺部浸潤的病人大部分症狀不明顯,然而仍有可能會導致嚴重的症狀甚至死亡。因為缺乏特別的影像學及實驗室檢驗特徵,白血症肺部浸潤在診斷上常十分困難,因此也常需要藉由一些侵入性的檢查才能更加確立診斷。病理上常會看到白血球滯留以及白血球的肺泡移行。在此分享一個因為白血症肺部浸潤而導致呼吸衰竭,需要呼吸器以及葉克膜支持的病人,而我們藉由肺泡沖洗術及超音波導引切片確立診斷。
