肺炎型细支气管肺泡癌的多排螺旋CT诊断价值

MSCT Diagnostic Value for Pneumonia-type Bronchioalveolar Carcinoma

目的:探讨肺炎型细支气管肺泡癌(PBAC)的多排螺旋CT(MDCT)表现及其诊断和鉴别诊断。材料与方法:对9例经病理证实PBAC的MDCT影像学资料进行回顾分析。结果:段性分布2例(22.2%),叶性分布5例(55.6%),弥漫分布2例(22.2%)。蜂窝征3例(33.3%),蜂窝征内实变影2例(22.2%);枯枝征5例(55.6%);血管造影征4例(44.4%);磨玻璃征5例(55.6%),其中3例(33.3%)磨玻璃影内见实变影;叶间裂膨隆征3例(33.3%)。结论:PBAC的MDCT表现具有一定特征性,全面分析其影像学特征,在诊断及鉴别诊断中具有重要临床意义。

Purpose： To study the Multi-detector computer tomography （MDCT） features of pneumonia-type bron- ehioalveolar carcinoma（ PBAC）, the diagnosis and differential diagnosis. Materials and Methods： The MDCT features of 9 cases of PBAC with pathologic results were retrospectively analyzed. Results： segmental distribution in 2cases（ 22. 2% ） , lo- bar distribution in 5cases（55.6% ） , diffuse distribution in 2cases（22. 2% ）. honeycomb sign in 3cases （33.3%） ; consol- idation in honeycomb sign was 2 cases （22. 2% ） ; dead-tree-branch sign in 5 cases（55.6% ） ; angiogram sign in 4 cases （44.4%） ; crude glass opacity in 5 cases （55.6%）, in which, 3 （33. 3% ）with consolidation ; bluging of interlobar fissure in 3cases （33.3%）. Conclusion： PBAC showed particularly characteristic signs on MDCT, comprehensive analysis of ima- ging features plays an important clinical role in diagnosis and differential diagnosis.
