1、肺部炎性假瘤CT阳性_肺部炎性假瘤的CT诊断 R816.4A16723783(2011)06003501 目的探讨肺部炎性假瘤的CT表现。 材料与方法 12例经手术和病理证明的肺部炎性假瘤。男7例,女5例,年龄2167岁,平均44岁。12例均作CT平扫及增加检查。 结果 CT平扫均表现为等或略高密度;4例界限清,8例界限模糊,团注碘佛醇100ml后增加扫描,动脉期8例界限模糊病灶周边轻到中度强化,4例界限清晰动脉期无强化;门脉期及延迟期均表现为周边环状强化及中心无或不均强化,3例内见线状分隔强化。结论 肺部炎性假瘤的边界及强化方式与其所处的病理阶段有关,动态增加扫描对其鉴别诊断有肯定的价值。
2、断层、X线计算机 肺部炎性假瘤 Inflammatory pseudotumor of the CT diagnosis Linjieguo Objective To investigate the pulmonary inflammatory pseudotumor of the CT. Materials and Methods 12 patients with surgically and pathologically confirmed pulmonary inflammatory pseudotumor. 7 males, 5 females, aged 21 to 67 years
3、, mean 44 years old. 12 cases were as plain and enhanced CT examination. The results are expressed as CT scan, etc., or slightly higher density; four cases of clear boundaries, 8 cases of blurred, Ioversol 100ml bolus after enhanced scanning, 8 cases blurred the boundaries between arterial lesions w
4、ith mild to moderate peripheral enhancement, four cases of boundary clear that no enhancement in the arterial phase; portal venous phase and delayed phase appeared as ring enhancement and central non-peripheral or inhomogeneous enhancement, three cases were seen in the linear separation strengthened
5、. Conclusion Inflammatory pseudotumor of the border and strengthen ways in which the pathological stage of its dynamic enhanced MRI differential diagnosis of some of its value. fault, X-ray computer Inflammatory pseudotumor 肺部炎性假瘤(pulmonary inflammatory pseudotumor, PIP)是一种良性病变,预后良好,但影像学表现缺乏特征性,常出现误
6、诊。本文收集我院经病理及手术证明的肺部炎性假瘤,对其CT图像进行回顾性分析,以提高对本病的相识。 1 材料与方法 2001年2010年我院经病理及手术证明的肺部炎性假瘤12例,其中男7例,女5例,年龄2167岁,平均44岁。临床表现为胸痛4例,不规则发热1例,7例无明显不适症状,体检发觉。3例曾做肺大泡切除手术。 所用机器为美国GE 公司Brightspeed 4排螺旋CT 扫描仪。扫描参数: 120kV , 250 280mA;增加扫描,运用单筒压力注射器,以3. 0ml/ s 的速率注入100ml 碘佛醇,注药后25s、60s及延迟90s 行三期扫描。所得图像均运用多平面重建(MPR)技术
