原发性气管癌的影像学诊断

 目的：提高原发性气管癌的影像学诊断水平。方法：进行8例原发性气管癌的X线、CT、MRI检查与临床病理对照分析。结果：8例影像学显示气管壁广基底菜花状或乳头状肿块影致管腔狭窄，肿块大小2~4.5cm，1例伴纵膈淋巴结肿大转移。病理诊断：气管鳞癌4例，腺样囊性癌４例。结论：MRI多体位进行气管癌检查，在显示气管癌的形态、大小、气管壁浸润、纵膈淋巴结有无转移等信息优于X线和CT，有助于临床治疗方法选择及预后判断。

Imagelogical Diagnosis of Primary Tracheocarcinoma

Objective:To improve imagelogical diagnostic level of primary tracheocarcinoma.Methods:X ray,CT and MRI examination were done and clinical pathology was analyzed in 8 cases with primary tracheocarcinoma.Results:The tumor appeared as follows:sessile cauliflower like or papillary mass with size of 2～4 5cm in tracheal wall resulting lumen stenosis,mediastinal lymph node enlargement with metastasis in 1 case.Pathological diagnosis:squamous cell carcinoma of trachea in 4,adenoidcystic carcinoma in 4.Conclusion:Different posture of MRI examination was superior to X ray and CT in shape,size,infiltration of tracheal wall and mediastinal lymph node metastasis of tracheocarcinoma.It was helpful to select clinical treatment and decide prognosis.
