Atrial myxoma is uncommon and may be associated with brief isolated ischemic events. We describe a patient with atrial myxoma and an incompletely evaluated ischemic stroke followed 1 year later with almost complete brain necrosis.
A 63-year-old woman presented with a rapidly progressive illness resulting in coma within 24 hours from multiple myxomatous emboli. Cranial computed tomographic scan demonstrated multiple hypodensities in both cerebellar and cerebral hemispheres. Postmortem examination revealed virtually complete brain necrosis, multiple peripheral artery embolizations, embolization in the coronary arteries with acute myocardial infarction, and tumor emboli in the spleen and kidneys.
Although uncommon, atrial myxoma may present as a fatal multiple organ embolization that includes both anterior and posterior circulation territories of the brain.
心房黏液瘤并不常见,可能与短暂的孤立性缺血事件有关。我们描述了一名患有心房黏液瘤且缺血性卒中评估不完整的患者,1年后出现几乎完全的脑坏死。
一名63岁女性因多个黏液瘤性栓子导致病情迅速进展,在24小时内昏迷。头颅计算机断层扫描显示小脑和大脑半球均有多个低密度影。尸检发现几乎完全的脑坏死、多个外周动脉栓塞、冠状动脉栓塞伴急性心肌梗死以及脾脏和肾脏的肿瘤栓子。
尽管罕见,但心房黏液瘤可能表现为致命的多器官栓塞,累及脑的前循环和后循环区域。
