目的探讨不典型肺脓肿的X线影像学特点。方法对37例不典型肺脓肿患者的X线影像表现进行总结分析。结果不典型肺脓肿可分为孤立团块型和不规则浸润型,本组有孤立团块影17例(45.9%),不规则浸润影20例(54.1%)。两型均具有以下共同影像学特点:①局限融解或小空洞。②局部充血征。③病灶周围局限浸润片影。④病灶边缘粗长索条影。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诊和鉴别诊断的关键。临床诊断时要将影像学特点与其他临床资料相结合来综合分析。
Objective To investigate the radiographic features of atypical pulmonary abscess. Methods The imaging findings of 37 patients with atypical pulmonary abscess were analyzed. Results Atypical pulmonary abscess could be divided into two groups: isolated lumps and irregular infiltrative types. There were 17 cases (45.9%) with isolated masses and 20 cases (54.1%) with irregular infiltration. Both types have the following common imaging features: ① local melt or small hole. ② local congestion sign. ③ lesions around the infiltration of film shadow. ④ edge of the rough edge of the cable video. ⑤ adjacent pleural thickening adhesions. Conclusions The existence of abscess cavity and the inflammatory changes around the lesion are the key points for the diagnosis and differential diagnosis. Clinical diagnosis of imaging features and other clinical data should be combined to comprehensive analysis.
