目的探讨多层螺旋CT(MSCT)在诊断房间隔瘤(ASA)中的应用价值。资料与方法根据瘤体膨出超过房间隔平面≥15mm或瘤基底部宽度≥15mm诊断ASA,回顾性分析9例ASA患者的CT表现。结果 8例瘤体突向右心房;6例位于卵圆窝水平。9例患者瘤体平均膨出15mm、瘤基底部平均宽度21mm。3例并发卵圆孔未闭及左向右分流。9例患者瘤体凹面及左心房内均未见血栓形成。结论 MSCT能直观显示房间隔膨出的形态、部位、大小及运动方式,可作为诊断ASA的一种简便、可靠的方法。
Objective To investigate the value of multi-slice spiral CT (MSCT) in the diagnosis of atrial septum tumor (ASA). Materials and Methods The ASA was diagnosed according to the tumor bulging over the atrial septal plane ≥15 mm or the basal part of the tumor ≥15 mm. The CT findings of 9 ASA patients were retrospectively analyzed. Results 8 cases of tumor protruding to the right atrium; 6 cases located in the ovum and fossa level. Nine patients had an average bulge of 15 mm and an average width of 21 mm on the basal part of the tumor. 3 cases of patent foramen ovale and left to right shunt. There was no thrombus formation in the concave surface of the tumor and the left atrium in 9 patients. Conclusion MSCT can directly display the shape, location, size and movement of atrial septal bulging, which can be used as a simple and reliable method to diagnose ASA.
