Metastatic pulmonary calcification is a frequent complication of chronic renal failure, especially in patients undergoing maintenance hemodialysis. We report a patient with chronic renal failure, who developed chest pain and hypoxia suggestive of pulmonary thromboembolism (PTE) and subsequently died. The ventilation/perfusion (V/Q) scan was also interpreted as consistent with PTE. At autopsy the areas of reduced perfusion on the scan corresponded to the areas of pulmonary calcification with no evidence of PTE. Physicians should be aware that this condition may mimic PTE, and that pulmonary angiography may be necessary to confirm the diagnosis prior to the initiation of anticoagulation.
转移性肺钙化是慢性肾衰竭的常见并发症，尤其是在接受维持性血液透析的患者中。我们报告一例慢性肾衰竭患者，该患者出现胸痛和低氧血症，提示肺血栓栓塞症（PTE），随后死亡。通气/灌注（V/Q）扫描结果也被解读为与PTE相符。尸检发现扫描中灌注减少的区域对应于肺钙化区域，未发现PTE证据。医生应意识到这种情况可能会模拟PTE，并且在开始抗凝治疗之前可能需要进行肺血管造影以确诊。
