Acute ischemic events secondary to pulmonary malignancy are rare. Those who present with acute peripheral arterial occlusions from malignant sources will typically have advanced pulmonary malignancy or myxomatous tumors. A 79-year-old woman had presented to Vancouver General Hospital with acute mesenteric ischemia. The pathology reports after embolectomy indicated cell morphology consistent with spindle cell carcinoma of the lung. Imaging investigations revealed a right upper lobe mass not present on chest imaging studies performed 14 months previously. The findings from the present report serves to remind us that acute ischemic events in the setting of no known history of malignancy or cardiac disease should prompt investigations into possible malignant sources.
继发于肺恶性肿瘤的急性缺血性事件很少见。那些因恶性来源导致急性外周动脉闭塞的患者通常患有晚期肺恶性肿瘤或黏液瘤。一名79岁女性因急性肠系膜缺血就诊于温哥华总医院。取栓术后的病理报告显示细胞形态与肺梭形细胞癌一致。影像学检查发现右肺上叶有一个肿块，而14个月前的胸部影像学检查未显示该肿块。本报告的研究结果提醒我们，在没有已知恶性肿瘤或心脏病史的情况下发生急性缺血性事件，应促使我们调查可能的恶性来源。
