摘要
目的探讨艾滋病(AIDS)合并卡氏肺孢子菌肺炎(PCP)的CT影像学特点。方法对确诊的31例患者,以入院首次肺部CT影像作为研究资料进行回顾性分析。结果入组患者CT影像呈双侧对称性分布者占93.5%,表现为弥漫性浸润者占96.8%。影像学表现:呈磨玻璃影者占100.0%、网织结节影者占51.6%、肺气囊者占41.9%、支气管双轨征者占35.5%、斑片状影者占32.3%、小叶间隔增厚者占32.3%、月弓征者占25.8%和碎石征者占16.1%。另外,实变影者占6.5%、胸腔积液者占3.2%。发生部位:磨玻璃影、斑片状影、支气管双轨征和碎石征以全肺叶分布为主、网织结节影、月弓征多发于肺下叶,肺气囊多见于肺上叶或上中叶。并存征象:CT表现为1种征象者占6.5%,2种者占16.1%,3种者占35.5%以及4种以上者占41.9%。结论 AIDS合并PCP的CT影像学表现复杂,多呈双肺对称性分布。磨玻璃影、网织结节影、碎石征、小叶间隔增厚和支气管双轨征是其常见征象,肺气囊和月弓征为其特异性征象。
Objective To investigate the CT imaging features of Pneumocystis carinii pneumonia (PCP) in patients with AIDS. Methods The CT images of 31 patients with PCP in AIDS were analyzed, retrospectively. Results The CT images showed that there were 96.8% patients with bilateral distribution and 96.8% patients with diffuse infiltration. A variety of findings of PCP were shown: the ground-glass opacity (100%), diffuse reticular pattern(51.6% ), air containing cystic pattern (41.9%), double-track syndrome (35.5%), patchy shadows (32.3%), lobular septum thickening (32.3%), moon low sign (25.8%), crazy-paving pattern ( 16. 1% ) , consolidation (6.5%) and pericarditis (3.2%). Location: ground glass opacity, patchy shadow, bronchial double-track syndrome, syndrome with lobar distribution mainly gravel, reticulocyte nodules and arch syndrome multiple were in the lower lobe of the lung, while pulmonary balloon multiple was in the upper lobe of the lung or lobe. The CT images showing 1 features were 6.5%, 2 features accouted 16. 1%, 3 features accouted 35. 5% and 4 features accouted 41. 9%. Conclusions The CT images of AIDS patients with PCP were complicated with a double lung symmetry distribution. The round-glass, diffuse reticular pattern, double-track syndrome, patchy shadows and lobular septum thickening were common and with moon low sign and crazy-paving pattern as its specificit.
