Extension of primary lung tumors into the left atrium via pulmonary veins is a well-documented phenomenon. Peripheral arterial embolism and cerebral embolism originating from a primary lung neoplasm are rare events. We report a case of simultaneous acute bilateral lower limb ischemia, bilateral renal infarction, splenic infarction and cerebral infarction as a result of multiple emboli originating from primary lung malignancy invasion of the left atrium. An emergent embolectomy revealed pathologic features of the extracted thrombus that were identical to the pulmonary neoplasm.
原发性肺肿瘤经肺静脉延伸至左心房是一种有充分文献记载的现象。源自原发性肺肿瘤的外周动脉栓塞和脑栓塞是罕见事件。我们报告一例因原发性肺恶性肿瘤侵犯左心房导致多发栓子形成，进而出现同时性急性双侧下肢缺血、双侧肾梗死、脾梗死和脑梗死的病例。急诊栓子切除术显示取出的血栓病理特征与肺肿瘤相同。
