摘要
目的探讨不典型肺结核的CT特点,提高对不典型肺结核的诊断能力。方法回顾性分析经手术及病理证实的CT表现不典型的肺结核54例。结果 3例表现为仅纵隔及肺门淋巴结肿大,6例表现为肺内孤立结节灶,3例表现为多发结节灶,15例表现为单发肿块影,27例表现为肺实变(15例)和肺不张(12例)。其中20例行增强扫描,表现环形强化7例、轻中度均匀强化4例,不均匀强化9例。54例中共误诊19例,其中7例诊为肺癌,3例诊为炎性假瘤,2例诊为肺段隔离症,7例诊为肺炎。结论不典型肺结核的CT表现多种多样,有时与肺癌、肺炎鉴别诊断困难,充分认识其CT表现,在诊断过程中密切结合临床及实验室检查,综合判断,可提高诊断准确率。
Objective To analyze CT manifestations of atypical pulmonary tuberculosis so as to improve the diagnostic ability for to atypical tuberculosis. Methods CT features of 54 patients with proved pathologically and clinically were reviewed. Results There were 3 cases showing just enlarged mediastinal and hilar lymph node,6 cases showing solitary pulmonary nodules,3 showing multiple nodules,15 showing mass,and 27 showing pulmonary consolidation and atelectasis. Enhanced CT scanning was performed in 20 cases,and 7 lesions showed circinate enhancement,4 showed slightly and middle enhancement,and 9 showed uneven enhancement. There were 19 cases were misdiagnosis. Among thorse,6 cases were misdiagnosed as lung cancer,3 cases were misdiagnosed as inflammatory pseudotumor,3 cases were misdiagnosed as pulmonary sequestration,and 7 cases were misdiagnosed as pneumonia. Conclusion There is a variety of CT manifestations of atypical pulmonary tuberculosis. Sometimes,it is difficult to identify atypical tuberculosis with lung cancer and pneumonia. Fully understaning CT manifestations and combining with clinical manifestations and laboratory examinations can improve the accuracy of diagnosis.
