肺血管瘤的影像学诊断

IMAGING DIAGNOSIS OF PULMONARY HEMANGIOMA

①目的 提高影像学检查 (X线、CT ,血管造影 )对肺血管瘤的诊断水平。②方法 对经过普通X线检查、血管造影和CT检查的 9例肺血管瘤病人 (其中 4例手术证实 )的影像资料进行分析。③结果 带有少许长条索的分叶状包块 ,其条索可与肺门血管相连为共有的征象。X线透视可见到病灶血管的搏动 ,做Valsalva和Muller试验 ,病灶大小有变化。CT检查示与肺门血管相连的长条索分叶状包块 ,平扫与强化扫描其密度变化与肺血管相似。血管造影示病灶呈囊状充盈 ,见到引入与导出的血管和肺静脉的提早显影。④结论 X线、CT与血管造影均可根据特征性征象对肺血管瘤做出准确诊断 ,但以血管造影为诊断本病的“金标准”。

Objective To improve the diagnostic accuracy of pulmonary hemangioma (PH) through X ray,CT, and angiography.\ Methods\ The information of 9 patients with PH (4 cases proved by surgery ) from X ray (fluroscopy, radiography, tomography), CT (plain and contrast enhanced scan) and angiography was analyzed.\ Results\ The common signs of pulmonary hemagioma were lobular masses with long strips connecting with the pulmonary hila. The vascular beating of the focus could be seen through fluoroscopy and the changes of lesions size through valsalva and muller examinations were visible. The plain and contrast enhanced CT scan showed no different changes on the density of PH. While by angiography, PH was filled with cystic shapes as well as early appearance of the leading in/out vessels and the pulmonary veins . \ Conclusion\ Angiography is a gold standard for the diagnosis of PH though both X ray and CT can also reach the goal.
