【摘要】 目的探讨不典型肺脓肿的影像学特点。方法重点分析３０例不典型肺脓肿的Ｘ线、ＣＴ影像表现。结果不典型肺脓肿可分为孤立团块型和不规则浸润型，且两型均具有以下共同影像特点：（１）局限融解或小空洞。（２）局部充血征。（３）边缘粗长索条影。（４）周围局限浸润片影。（５）邻近胸膜增厚粘连。结论明确脓腔的存在和病灶周围的炎症性改变是确定诊断和鉴别的关键更多还原

【Abstract】 Objective Evaluate characteristics of the radiological image of atypical pulmonary abscess. Method The X ray and CT image in 30 cases with atypical pulmonary abscess were analyzed. Result The atypical pulmonary abscessses were classified into solitary ball type and irregular infiltration type. And these two types showed the following characteristics: circumscribed dissolution or small cavity; local congestion sign; coarse and long funiform shadow in margin; ambient circumscribed infiltrating shadow; adjacent pleural thickening and adhesion. Conclusion Existence of abscess and perifocal inflammatory changes is the key to diagnose and differentiate this atypical variant of lung abscess.更多还原
