左心耳血管瘤临床及影像特征

Clinical and Imaging Characteristics of Hemangioma in the Left Atrial Appendage

目的回顾本院及国内外文献中左心耳血管瘤患者的临床及影像资料,提高对其认识水平。方法报道1例来自遂宁市中心医院的左心耳血管瘤患者,同时系统检索国内外主要数据库中与此主题相关的中英文文献,收集并整理临床及影像资料。结果共纳入10篇中文和外文文献,包括9名女性和2名男性,平均年龄为64岁。肿瘤的最大直径范围集中在4.0~6.3cm(7例),CT增强扫描主要表现为“渐进性强化”方式,术后病理检查以海绵状血管瘤型最为常见(7例),外科手术切除术后预后良好患者约占63.6%(7例)。结论左心耳血管瘤非常罕见,影像学检查可为临床手术切除肿瘤提供指导,患者术后预后良好。

Objective To review the clinical and imaging data of patients with hemangioma of the left atrial appendage from our hospital and the literature at home and abroad,and to improve our knowledge of it.Methods A case of hemangioma of the left atrial appendage from the Suining Central Hospital was reported,and literature review in the main Chinese and English databases on this topic was also performed.Both clinical and imaging data of these patients were collected.Results Three Chinese and seven English documents with 9 females and 2 males were included,with an average age of 64 years.The maximum diameter of the tumors was 4.0-6.3cm(7 cases).At enhanced CT scan,cardiac hemangioma mainly shows a patten of“progressive enhancement”.Postoperative pathological examination showed that cavernous hemangioma was the most common type(7 cases).About 63.6%(7 cases)of patients had good prognosis after surgical resection.Conclusion Hemangioma of the left atrial appendage is very rare.Imaging examination can provide guidance for surgical resection,and most of the patients will have a good prognosis.
