ABSTRACT
We report a case of lymphoma that happen in the right atrium. It is so rare in the heart tumor. We analysed the CT and US manifestation. It is so important to diagnosis this disease early for the closely relation to the prognosis. In this case we can not find necrosis and calcification in the tumor. We should different lymphoma from other heart tumor such as vascular sarcoma, myxoma etc. It is very important to realize this kind of disease as a radiologist.
Key words: Lymphoma; Heart tumor; CT; Ultrasonography
心脏原发淋巴瘤很少见,影像学明确诊断对于治疗方法的选择及患者的预后关系意义重大,现将本院活检病理证实的一例心脏淋巴瘤报道如下:
患者,男,22岁,主因劳累后胸闷,憋气四个月入院。患者四个月前无诱因劳累后憋闷,气促,咳白痰,休息后缓解,夜间加重,不能平卧,无发热、寒战、盗汗,无晕厥及蹲距现象。15年前曾患脑炎,无特殊家族史。体检:重病容,颈静脉怒张,颈动脉博动异常加强,呼吸急促,血压110/70mmHg,心界左下扩大,120次/分,率齐,心音低,未闻及杂音,未扪及震颤,腹平软,全身浅表淋巴结未及肿大,余无特殊。心电图:窦性心动过速,不完全右束支传导阻滞,顺时钟转位。
影像学检查
一、CT所见
右房内充满软组织密度肿块,平扫CT值46HU,增强CT值67.71HU,增强后右房残腔明显不规则, 肿物未见出血及坏死征象。肿块向上包绕上腔静脉,致管腔变窄,胸椎旁奇及半奇静脉扩张,上纵隔侧支形成;肿物沿右房上部及后部蔓延至肺动脉及下腔静脉开口处,并向纵隔内延伸,左房受压体积变小,主动脉根部亦受到推压,双侧心室未见累及。大量心包积液及双侧胸腔积液,双下肺压迫性肺不张。气管支气管开口通畅,气管支气管前方可以小淋巴结肿大。
二、CT诊断
右房占位,首先考虑血管肉瘤,淋巴瘤不能除外,上腔静脉受侵,心包积液并双侧胸腔积液,双下肺压迫性肺不张。
三、心脏超声
房间隔,右心房顶端探及中等实性回声,表面欠规整。心包腔内液性暗区。
1. 右心房实性占位。
2. 大量心包积液。
开胸探察,手术所见:
(1) 右心房内充满大块实性占位,质硬,左房壁厚,上下腔静脉受累,升主动脉根部受累,右肺门被肿瘤及炎性组织包绕。 |
