摘　　要：目的研究肺脓肿的CT征象特点和鉴别诊断。方法搜集66例经临床证实的肺脓肿患者的CT与X线检查资料,并进行回顾性分析。结果66例肺脓肿患者的主要CT表现是:(1)近心型:病变较小即可形成液气平面,内壁可不规则;(2)周围型:早期病变中心有坏死低密度区,无气液平,内壁光滑;(3)病变边缘有锯齿状、毛发状改变但较模糊;(4)周围型胸膜有较广泛增厚;(5)抗炎治疗后病变明显吸收缩小。结论CT检查对肺脓肿的正确诊断与鉴别诊断具有较高的价值。Objective To study CT signs of pulmonary abscess and to investigate its value on differential diagnosis. Methods The CT and X-ray data collected from 66 patients with clinically proved pulmonary abscess were analyzed retrospectively. Results Main CT appearances of pulmonary abscess were summarized as follows： （1） Gas-fluid plane was frequently found in the abscess adjacent pulmonary hilum even if it was smaller, and its inner wall could be irregular. （2）Central liquefaction necrosis was formed earlier in the peripheral abscess, which appeared low-density shadow on CT. The inner wall of cavity was usually smooth and gasfluid plane was not frequently seen. （3） Their outer walls usually had cog-like or hair-like outlook, and their margins were unclear.（4） Extensive pleural thickening was frequently found in the peripheral lesions. （5） All the abscesses were absorbed to smaller after regular anti-infectious treatment. Conclusion CT plays an important role in the diagnosis and differential diagnosis of pulmonary abscess.
