摘要
目的 :探讨肺炎性假瘤的影像特点及其误诊原因。方法 :回顾性分析 46例经病理证实的肺炎性假瘤的CT表现。结果 :40例误诊为肺癌 ( 87% ) ,6例误诊为结核球或良性肿瘤 ( 13% )。结论 :CT对肺炎性假瘤的诊断有一定的局限性 ;多发病灶或合并肺门纵隔淋巴结肿大者的诊断更为困难 ;没有活检 ,诊断时过分强调某个CT征象或临床症状 。
Objective:To investigate the CT findings of inflammatory pseudotumour and analyze the cause of misdiagnosis. Methods: The CT features of 46 cases of inflammatory pseudotumours confirmed by operation and pathology were reviewed and analyzed.Results:40 of 46 cases were misdiagnosed as lung cancer (87%),and the remaining 6 ones misdiagnosed as tuberculoma or benign tumor (13%).Conclusion:CT is limited to some extent in making a correct diagnosis involving pneumonic pseudotumour,especially with the enlargement of the hilar and mediastinal lymphs node.Biopsy overemphasis on a certain CT feature or clinical symptom and paying little attention to comprehensive analysis are the main cause leading to misdiagnosis.
